Toyota 1997 4Runner Headunit DIY

[ivopivo]

I wanted to write this to hopefully help someone else in need of a DIY with more photos, etc.

Insert the "Do this at your own risk, I'm not responsible for hospital bills or car explosions" Note here.

Over the years I've come to realize doing almost anything on cars is much simpler than it appears at first, but I also always like to have as much info as possible before starting a project, so here it is.

I purchased an Alpine headunit (single din) that came free with 2 harnesses, a tray to go under the headunit and full set of easy to follow instructions.

I didn't take any photos splicing the wiring harnesses together. This can be done a number of ways, so I didn't really want to get into it. I simply use electrical tape and a razor blade. Sounds "caveman-like" but works perfectly and looks decent. Simply expose 1/4-1/2" wires (the Alpine harness came with fully insulated wires whereas the 2 harnesses that connect to the car had trimmed insulation already, or Vice Versa I forget now), twist them together, bend down onto its own insulation and cover with a couple loops of electrical tape. Do this individually for each 2 wire connection of course and then at the end I tape all the wires together so they're not flying around in the back of the unit/dash. I have done at least 10 units this way over last 10 years and had absolutely no issues. The nice and more correct way to do it is to use a combination of 1 or all of these... small wire nuts, solder, heat-shrink, etc. Again, whatever you do make sure to take all precautions necessary to not electrocute yourself and not blow up your car later.

I used the following links for reference (they all have great pointers that helped me know exactly what to do).

NOTE: I used a few photos from the above links in my DIY below (credited the members who took them, Mom and CoFlyFisher) so if that's against the rules I can remove them. Hope they don't mind.

Once I started working on mine I realized it was a piece of cake job so I wanted to take photos and make a nice DIY. I'll try to be as detailed as possible in photos and descriptions, but there are 3-4 photos I wish I had and didn't get. No big deal at all.

FAIR WARNING: There are 60+ photos, so let them load before you think something is crashing

All photos can be seen in my album here (https://www.flickr.com/photos/130074049@N07/albums/72157661280821838/with/37526532326/), but I'll link them all below so it's easier to follow the DIY.

Lastly, some photos were taken at the "wrong times" but they still explain the step well. For example, I took photos of the trim removal and some other things while putting things back together rather than initially taking them apart, but I promise it's exactly the same .

Onto the actual install...

Here are all the tools I used... For the headunit install, all you need is a phillips screwdriver (drill makes things quicker, just be careful when reinstalling), flat screwdriver or anything else to pry things and a knife/razor/blade to trim wire insulation when connecting the harnesses. A magnet is a good idea to help removing one bolt in particular so it doesn't fall into the dash. I used the 10mm socket to loosen trim under the steering column, but this is only because I was installing a microphone with my headunit. I used the rest of the stuff for my clock fix/soldering.

First thing you do is lift the e-brake and open the center console compartment to allow removal of the trim piece. Then you simply lift up on the tray/trim around the e-brake. There are clips in the front by the shifter...

Couple at the top by the compartment and a couple in the middle where it bends...
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/37575220941/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (2)"><img src="https://farm5.staticflickr.com/4443/37575220941_ace20b92bb_h.jpg" width="768" height="1024" alt="Toyota 1997 4Runner Headunit Install (2)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

Once all are unclipped, just slide it over the e-brake handle and put to the side (no need to disconnect any of the stuff under there, unless for some reason you decide to sit in the driver seat while working, in which case you can just put this on the passenger side of course)

Then lift up from the back on the trim around the shifter.. Same concept here, a few clips but comes right up. I didn't remove this piece, rather just unclipped and pulled a bit to the rear to allow removal of the big center trim piece that surrounds the headunit, AC, etc...

Next, remove all the little knobs for the AC controls... (Note: Putting all the control levers to the center helps in both removal and installation of the face plate)
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/37575220451/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (8)"><img src="https://farm5.staticflickr.com/4461/37575220451_c7e29be472_h.jpg" width="1024" height="768" alt="Toyota 1997 4Runner Headunit Install (8)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

MISSING PHOTO... I forgot to take a photo removing the AC control face plate... I copied 1 photo here from user Mom's DIY linked to above, which clearly shows how to remove the plate. I used a small plastic blade, but anything fairly thin and somewhat hard will work.. butterknife, etc. Just make sure to protect the plastic if using anything sharp

The A/C button will come off with the face plate. This is perfectly normal as you'll see in the photos below how it plugs into the back of the actual control unit. This will also be your guide for reinstalling the face plate...

Here is the faceplate removed... We'll be removing the two screws in order to free up the center console trim...

One screw is on the lower right of the AC unit...

The other is on the left side of the AC unit and recessed/hidden, so it's best to use a magnetized bit in order not to drop it. This is all the high tech I had at my disposal...

[ivopivo]

I did try both removing and reinstalling the screw with just the magnet to get it going, but it was definitely not strong enough to start the threads. (After re-reading this to make sure it looks good I realized how dumb this sounds so wanted to clarify... I tried using the magnet AFTER just about fully removing the screw with a screwdriver and when reinstalling BEFORE actually tightening it just to get it going... In other words, I didn't sit like an idiot twisting a magnet trying to remove the screw that was tightly screwed into the dash haha)
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/23722946768/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (16)"><img src="https://farm5.staticflickr.com/4481/23722946768_1396fc575a_h.jpg" width="1024" height="768" alt="Toyota 1997 4Runner Headunit Install (16)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

Here is the empty hole from which the left screw was just removed... Ignore the screw below that, we're not touching that for this DIY...
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/23722946688/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (17)"><img src="https://farm5.staticflickr.com/4475/23722946688_34decb503f_h.jpg" width="1024" height="768" alt="Toyota 1997 4Runner Headunit Install (17)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

Once the screws are removed, only a few clips (I think 6 total) are holding in the center trim piece. To remove, best is to push in the top vents so they face down, then grab the piece by the vent holes and just below the cup holder.
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/23722946568/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (18)"><img src="https://farm5.staticflickr.com/4489/23722946568_4c154278ae_h.jpg" width="1024" height="768" alt="Toyota 1997 4Runner Headunit Install (18)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

This should easily release the top and middle clips (as shown in this photo by CO FlyFisher)

Here are photos of the bottom clips. When reinstalling, it's best to start with these clips so you can align everything from the bottom up
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/23722946498/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (19)"><img src="https://farm5.staticflickr.com/4485/23722946498_5c622f1552_h.jpg" width="1024" height="768" alt="Toyota 1997 4Runner Headunit Install (19)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

Once all 6 of the clips are undone, these 3 connectors are still attached (1 for clock, 1 for defroster and 1 for emergency/flashing lights). They're plugged into their ports in this orientation, so remove the top two first, then the bottom one for the clock...
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/23722946368/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (21)"><img src="https://farm5.staticflickr.com/4473/23722946368_87e5d0e992_h.jpg" width="1024" height="768" alt="Toyota 1997 4Runner Headunit Install (21)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

Once those 3 connectors are loose, you can rotate the large center trim piece forward, but DO NOT pull on it yet as it's still attached at the 12v outlet and the light bulb on the ashtray.
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/23722946318/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (22)"><img src="https://farm5.staticflickr.com/4485/23722946318_7b0f0c3699_h.jpg" width="1024" height="768" alt="Toyota 1997 4Runner Headunit Install (22)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

(NOTE: At this point, it's possible to do the headunit installation without fully removing this trim piece. However, access to the amp below the stock headunit (if your 4Runner has one) is fairly tight. I also wanted to clean up the rear of the center trim piece because it was extremely dusty as you'll see in photos below, so I decided to remove everything).

There are two connectors on the 12v outlet (one is an "L" shape and just pulls out I believe, whereas the other has a small latch on the connector) and the bulb on the ashtray.

The bulb simply pulls out...

Mine was dead but I didn't care to replace it so I just tossed it in the trash...

Two connectors on the 12v are off...

Note: After removing all connections, you will need to turn the car to ON position and move shifter all the way back in order to remove the trim piece over the shifter. Otherwise there's no room to pull it up in front of the shifter when it's in Park.

And now the piece is gone and we have access to everything...

Here you can see all the dust on the back of the trim piece, ashtray, vents, etc...

I decided to fully clean up the entire piece...

And also cleaned up inside the dash as much as possible as it had 250k miles worth of Arizona dust!

Now onto the headunit removal and installation... Once the big piece is out, put the shifter back in park and turn off the car/ignition.

There are 2 screws on the left of the stock headunit...
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/37526529406/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (33)"><img src="https://farm5.staticflickr.com/4472/37526529406_5fe13ffa22_h.jpg" width="1024" height="768" alt="Toyota 1997 4Runner Headunit Install (33)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

And 2 to the right...
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/37543084022/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (34)"><img src="https://farm5.staticflickr.com/4511/37543084022_3f098c0900_h.jpg" width="1024" height="768" alt="Toyota 1997 4Runner Headunit Install (34)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

Once those are removed, pull the headunit forward and you'll see 3 connections in the back. The closest to the camera is the antenna, which I plugged into my new Alpine headunit when reinstalling. The second one, that looks like a thinner antenna connector, I didn't use and didn't really look into its purpose (If someone knows please post as I'm curious what purpose it served). The third to the rear is a connector for the headunit...
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/37526529176/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (35)"><img src="https://farm5.staticflickr.com/4463/37526529176_eab0aeff69_h.jpg" width="768" height="1024" alt="Toyota 1997 4Runner Headunit Install (35)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

This is the connector that goes to the headunit from the amp.
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/37316560770/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (36)"><img src="https://farm5.staticflickr.com/4480/37316560770_47d430a2c8_h.jpg" width="768" height="1024" alt="Toyota 1997 4Runner Headunit Install (36)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

At this point I was confused and worried for about 2 seconds because I realized my Alpine unit was send with 2 harnesses. I quickly remembered BigRodger's post mentioning the Amp, so I looked at the Crutchfield instructions and they did note removal of the stock amp if you have it. Here is the amp in the back, below the headunit. You need to remove the two screws holding the amp bracket and it comes out...
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/37526528976/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (37)"><img src="https://farm5.staticflickr.com/4470/37526528976_dd98bc7236_h.jpg" width="1024" height="768" alt="Toyota 1997 4Runner Headunit Install (37)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

Once it's loose, flip it over and remove the two connectors on the back of the amp...
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/37316560560/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (38)"><img src="https://farm5.staticflickr.com/4484/37316560560_0dbc6b4527_h.jpg" width="1024" height="768" alt="Toyota 1997 4Runner Headunit Install (38)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

Here is your new paperweight...

These two connectors plugged into the harness which Crutchfield provided.
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/37526528586/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (41)"><img src="https://farm5.staticflickr.com/4480/37526528586_4dfae285c1_h.jpg" width="1024" height="768" alt="Toyota 1997 4Runner Headunit Install (41)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

I decided to just screw in the amp to its original and final resting place so as not to have to store it, sell it, lose it or throw it away...
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/37316560210/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (42)"><img src="https://farm5.staticflickr.com/4507/37316560210_9abedf4b5b_h.jpg" width="1024" height="768" alt="Toyota 1997 4Runner Headunit Install (42)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

For this headunit and this installation (I believe because it has the stock brackets) the sleeve for the new headunit isn't used so I had to remove it with the typical tools they provide...
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/37526528366/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (43)"><img src="https://farm5.staticflickr.com/4458/37526528366_90193dab44_h.jpg" width="1024" height="768" alt="Toyota 1997 4Runner Headunit Install (43)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/37316559960/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (44)"><img src="https://farm5.staticflickr.com/4491/37316559960_d050150910_h.jpg" width="768" height="1024" alt="Toyota 1997 4Runner Headunit Install (44)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

Next, remove the brackets from the stock radio. There are 4 screws holding each bracket...
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/37526528216/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (45)"><img src="https://farm5.staticflickr.com/4502/37526528216_90a77c89a6_h.jpg" width="768" height="1024" alt="Toyota 1997 4Runner Headunit Install (45)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

Once removed, install the brackets onto the new headunit and position the included tray correctly. You will only be using 2 screws per side, so I screwed the 4 left over screws back into the stock radio.
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/37526528046/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (46)"><img src="https://farm5.staticflickr.com/4482/37526528046_5c2d6e4761_h.jpg" width="1024" height="768" alt="Toyota 1997 4Runner Headunit Install (46)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

I installed one bracket, positioned the tray, then bent the other bracket a bit so it goes easier into the tray, and finally screwed that to the other side of the headunit... Very easy just takes a little orienting to make it fit...

[ivopivo]

Now the easy part... Connect the two connectors from the already spliced harness to the car...
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/37575217321/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (50)"><img src="https://farm5.staticflickr.com/4454/37575217321_6093a021b7_b.jpg" width="1024" height="768" alt="Toyota 1997 4Runner Headunit Install (50)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

The black end of it goes into the Alpine headunit of course...
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/23722943748/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (51)"><img src="https://farm5.staticflickr.com/4514/23722943748_558d1cbc61_b.jpg" width="1024" height="768" alt="Toyota 1997 4Runner Headunit Install (51)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

The antenna connector plugs into the new headunit (the other one I taped off and left behind the dash to keep the amp company)...
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/37575217121/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (52)"><img src="https://farm5.staticflickr.com/4453/37575217121_1fd3c247b6_b.jpg" width="1024" height="768" alt="Toyota 1997 4Runner Headunit Install (52)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

NOTE: Before installing the new headunit, wire and plug in your microphone or any other audio stuff that you're installing. Mine came with a microphone, which I'll show in just a bit.

Once everything is connected, you're going to start the "reversal of all the removal steps"... Start by screwing in the new headunit with brackets...
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/23722943618/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (53)"><img src="https://farm5.staticflickr.com/4454/23722943618_48ab8577bf_b.jpg" width="1024" height="768" alt="Toyota 1997 4Runner Headunit Install (53)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

NOTE: I also did the fix on my clock which wasn't working, so if you're doing that definitely do it with the big center trim still off. Simply remove the clock from it, do the DIY fix, then proceed with steps below
NOTE: Sorry for all the notes

After the unit is in (and Clock fixed if you're doing that), you're going to put back the big center trim piece. Start again by ignition ON, shifter back, place the trim piece over the shifter and once you have the trim piece in place, you can put the shifter back to Park and turn ignition OFF. Connect the 12v and ashtray bulb, rotate trim piece up, then connect the 3 connectors up top and align all the clips, then press it in. Finally, reinstall the two screws holding the trim to the dash, reinstall the AC face plate (start with AC button/plug to guide it in) and put back all the little knobs on the control levers.

The trim around the new headunit doesn't fit, so you'll leave that off...

Attach the Alpine face to the unit and you're in business!

Photo to include the working clock as well...

After I was all done with the headunit and clock, I decided to wire the microphone... Before putting the new headunit in, I wired the microphone under the steering column and into the dash to plug into the headunit...
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/23722943268/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (57)"><img src="https://farm5.staticflickr.com/4506/23722943268_022ef63288_b.jpg" width="768" height="1024" alt="Toyota 1997 4Runner Headunit Install (57)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

I then simply tucked in the excess wiring under the steering column, behind the trim piece (need to undo the couple 10mm bolts for the trim) and placed the mic in the shown location...
<a data-flickr-embed="true" href="https://www.flickr.com/photos/130074049@N07/23722943218/in/album-72157661280821838/" title="Toyota 1997 4Runner Headunit Install (58)"><img src="https://farm5.staticflickr.com/4500/23722943218_3447eb0a8b_b.jpg" width="1024" height="768" alt="Toyota 1997 4Runner Headunit Install (58)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script>

FINALLY (man it took me at least 3x longer to do all the photos, host them, link them and write this than it did to do ALL of the actual work), here's just a quick bonus for those also fixing their clocks.

I wanted to try something different than the fix done by "Mom" and others, so I tried soldering the springs to the pins...

This did not work, probably because I didn't stretch the springs to make good contact. After this failed attempt, I did the simple soldering of the pins to the circuit board and then put everything back together. Clock works perfectly now, for how long I'm not sure.

I hope this helps someone, I'm off to take a 3hr nap now!

Thank you, this was really helpful, just threw a boss radio in mine and used the scoche car stereo connector kit.
