Stereo Wiring Harness

2000 Tundra SR5 V8 Access Cab
Does anyone have or know where to find a breakdown of the wiring harness coming off of the amplifier? I have removed the factory head unit and am left with a 20 pin plug that has 13 wires going to it. I have not been able to find an accurate breakdown of which wire does what. Any help is appreciated!

Hopefully this can shed some light on the subject....

All 13 wires are identified on the diagram.

 

Thanks. It sheds some light, but there is still a bit that is hidden. The colors of the wires in my wiring connector are different from what is in the provided schematic (see photos). I would prefer to figure this out before I start cutting and splicing wires. Any ideas?

 

is your amp below the factory radio? if so the normal toyota radios are plugged into that amp

 

Can I ask why you're cutting wires? There's adapters for under $10 so you can leave the factory connectors.

 

Where are u located? I have an adapter wiring harness (i ordered one on Amazon, then shortly realized best buy carries them, so now i have an extra one) that u can for free lol. Or you can buy one for 3 dollars on amazon and not have to cut stuff lol

 

I like this idea....

 

Are you saying that the pre-amp should be bypassed, then? The factory configuration has the head unit plugging into a pre-amp, which has the 13-wire connector coming out of it. The pre-amp has 2 other connectors going into it.

Factory configuration:
2 connectors -> pre-amp w/ 13-wire connector -> factory head unit

Proposed configuration:
2 connectors -> aftermarket harness adapter -> aftermarket head unit (Blaupunkt Baltimore)

Does this seem like it would work?

 

Blaupunkt is German. Germans make good stuff. @Pucks18 post up a link or pic of your adapter.

 

Thanks for the tip. I'll get one and let you all know how it goes.

 

Bypass the factory amp, the harness pictured above my post will plug into the 2 plugs that are plugged into factory amp.

 

@CDavis108 fyi, its a pain in the ass getting that amp out and those two screws!

 

When I installed stereos back in the day, that amp stayed in the truck. It was much easier to unplug the harness, bypass the amp and leave the amp where it was.

 

if the amp is right below your radio, yes

 

Make sure u keep ur oem radio unit so for when these trucks are worth 100,000 dollars in 70 years

 

After barking up a lot of wrong trees, I have finally gotten the stereo wiring harness sorted out. The amplifier needed to be bypassed in order to reveal the wiring connectors to which my wiring adapters connected. Thanks to everyone who contributed info.

I also added a back up camera since the new head unit could accommodate. Why not, right?

 

I really would love to know how you did that.im new to this and am stumped at the moment.

 

Start by filling out your profile to list what year and type of cab your (dad's?) truck is, "regular", "access" or "double".
Then go create your own thread asking for help with whatever you need help with.
It would help to know if your truck has tweeters in the front door, and if you see "JBL" anywhere on the radio face.

Whatever you do, DO NOT cut the factory harness(es).
