I bought my 85 4runner last weekend, and it didn't have a radio, so I bought an Alpine to replace it. I have no idea how to wire this thing up, can anyone help me?

Thanks man, I appreciate it. Most of the wires are 2 toned main color is pale green with a stripe of a different color so I am guessing those are the colors the chart is referring to.
 
Go to your local Radio Shack or Wally World and get a vehicle specific adapter harness, makes it a lot easier.
 
Walmart sells the correct harness for like 15 bucks, makes it alot easier and faster to install

Ok thanks, Ill probably run by there in the morning, I've got to call Toyota in the morning too and have them order me a mounting bracket.
 
The adaptor Wally World and Crutchfield have is for 1986 up Toyotas. and they are the same at both stores. There must have been a change in the color codes. Try checking the 85 FSM at North Carolina Toyota Territory Off-Roaders Association

The brackets you need are on eBay used. One set right now is only $17. Try searching eBay for "4Runner radio bracket." I get a lot of stuff from eBay and it usually arrives 2-3 days after I pay for it.

I just did a new radio in my 00 4Runner last week and noticed the wire adaptor was not for 85 and older Toyotas.

I also bought 4 nuts I needed from Toyota last week and it was over $12 for them and they took two days to arrive at the dealer. I can't imagine what they charge for the radio bracket.

FWIW the Radio Shack nearest to me no longer sells stuff for automotive sound. They are all about selling TV's and cell phones. I was looking online for an antenna for my 1st gen and they had one "online only."

I ordered my brackets today, part of the problem was the previous owner pulled the fuse for the cigarette lighter and the clock hooked that back up so now I am still trying to figure out all of the wiring.
 
Something else I noticed is that there aren't enough wires for everything, I am guessing that I will have to run new wires the the rear speakers.
 
As far as I know the radio surround is the same in 84-89 4Runners.

Is your 4Runner a DLX ? Mine is an 89 DLX and they did not come with rear speakers but the grill holes are there in the rear. In most cases Toyota left wires for accessories but they did not leave wire for the rear speakers.

I found the wiring color codes:

I love Google.

Yes it is, that is probably the reason, I guess I'll be running some speaker wire tomorrow.
 
just installed a stereo into my son's 88 4runner yesterday. had to figure out the hack-job wiring that was in there. but..we also put 4 new speakers in and ran new wires. it all came to a stop when I was puzzled by the wiring.

found this link...------>>> 1988 Toyota 4Runner Car Stereo Wiring Schematic tried to download (DO NOT...because it added all kinds of crap to my computer) but I found a VERY good explanation of what wires are what(have to look a bit down on the page)....and it was perfectly accurate. and with that, our install is complete.

EDIT...I am new to this forum, but you can find me on YOTATECH (same screen name). not sure why there is an ad in my sig here. not used to that.


EDIT #2 looks like I was able to copy and paste what I was talking about
