So here are the parts I used for my install of my Pioneer AVH-P2300DVD Head Unit in my 2004 Toyota 4Runner SportEdition (Stock, non-Nav). I had to do a lot of research to find all of this information and I hope that if anything it can help someone out since it took me quite some time to compile a lot of this information from searching all over this website and others.

First off, I went to Best Buy to see what an installed unit would cost, after parts and labor it was north of $700 for the same set-up, installed myself for just barely over $300.

Parts list -

-Pioneer AVH-P2300DVD (Amazon)
-Metra 95-8202 Toyota DDIN Multi Dash Kit (Amazon)
*Best Buy was looking for the 8210, which thankfully in doing research I found out WILL NOT FIT. The 8202 fits like a gem!

-SCOSCHE TA02B Wiring Harness for 1987 and up Toyota (Amazon)
-Metra AXXESS ASWC Universal Wheel Control Interface (Amazon)
-Brake Bypass (eBay)

With a little research, for those of you who have the JBL Systems, you will need this item as well.
-Toyota TURN-ON Adapter TYTO-01

For wiring Diagrams I used The Install Doctor It was spot on in exception of the Orange Wire (Which indicates "DO NOT USE"), I hooked up to Orange/White "Illumination" on the Pioneer Harness.

I then used the Castulucci Guide to take apart the dash, worked like a dream.

Most importantly came the most frustrating part of the install, getting the AXXESS ASWC Interface to work. So here are the most important pieces of information to have.

First, pay attention to the install guide (Just for example, this was for my 2004):
8215 Shell Wiring Guide: The guide is actually opposite of what it needs to be. Instead of being from Left to Right, it actually goes Right to Left.

6 = White and Red (Ground)
7 = Violet and White (Control)
8 = Yellow and Black (Control)

Second, and most important for this to work: When you ground White/Red (Pin 6), make sure that you ground it with the same ground wire that you spliced into from the AFTERMARKET SIDE of the wiring Harness. I made the mistake of splicing into the grounding wire from the 4Runner side BEFORE the clip. Finally after some research, I was able to figure out where I made my mistake. I fixed it and reset the unit and it worked flawlessly.

To clarify the step above: If you install the Brake Bypass like I did, you will actually have a 3-way splice BEFORE the solder between the Headunit and OEM Wiring Harness. One for the ground for the AXXESS, one for the ground for the Steering Control and one for the Brake Bypass.

Third, the rest of the instructions for the AXXESS AWSC were easy to follow in the sense that Violet/White (Pin 7) matched up with the Green/Orange. And the Yellow/Black (Pin 8) matched up with the Black/Green.

If you have an Eclipse or Kenwood unit there are a couple of other wires that you will need to connect. But it's all very self-explanitory in the Install Guide.

For the Brake Bypass install, this was INCREDIBLY simple.
Performance Electronics Brake Bypass Install - 3 Wires.

Hope this helps someone else. I'm sure there was already a post similar to this, but I had a hard time finding it! Hope this is a good way to make my way into the T4R community!

Cheers!

valuable, thank you !

good info, thanks

Very informative post, thanks!

I'm installing an AVH-3200BT in my 04, replacing the non-JBL and no RDS factory unit.
I have a question regarding the blue/white wire on the pioneer harness.
I'm getting a bypass from eBay, it was easier for me to buy as I would have had to buy extra wire besides the relay so that's why I went that route.
Anyway... I know I have to connect the blue wire from the relay to the blue/white wire on the pioneer harness. Question - do I need to connect these 2 wires to the blue wire on the scosche harness (TA02B)?
I've read that you do need to use the blue wire if you have an antenna amplifier and that windshield antennas do indeed use an amp.

That's one reason I like Crutchfield. You decide on what system you want...They have a list of all the parts you'll need. And at Crutchfield...if you buy a car system from them...the parts (brackets, wiring...etc..) are free.

I was going to buy from Crutchfield but they don't sell the AVH-3200BT anymore. The newer Pioneer models no longer have SD Card slots. (a step backwards IMO)
I also had a $100 gift card from Amazon and they still had a few of those 3200BTs left.

This is how I wired the relay.

So you didn't use the blue wire from the Scosche wire harness?

EDIT: After watching that video in the OPs post, I do believe that you need the blue wire from the harness for power to the antennas because of that diversity system Toyota uses.

I got my relay from eBay yesterday (sure is small compared to using a standard relay!). Now I'm just waiting on the antenna adapters so I can plug both of them in. I think I'll try to do the install this weekend. The weather is supposed to be a bit rainy this week and I'd like to do the install out on the driveway with the sun shining.

Great info here, I am getting ready to do my head unit install and found some good info. Thanks for posting

OP

Does this mean your SE did not have the JBL system???

Seems like that is what you are saying.

thx

what relay did you get?

Instructions for wiring it in are on the eBay page.

What did you do with the extra antenna wire? My radio reception is poor after I installed my 3300BT

I haven't done my install yet, but I did find out some things about those 2 antenna wires.
You do need to hook both up wires, you can use the METRA Ltd 40-UV43 Motorola Antenna Y-adapter and the Scosche Mda-B Micro/Delco Antenna Adapter Tip. I believe the adapter tip goes on the smaller antenna plug, then both go into the Y-adapter and finally that goes into the back of the unit.

You can get both adapters from Amazon.

Wait, there's 2 antenna wires? That's the first I've heard of it
