Does anyone have access to the wiring color codes and what they control for the harness that runs at the bottom of dash on the drivers side. Thanks.

 

This what I have:

 

Thanks for the info. The colors don't seem to match up. Anyonle else have any info. on this harness.

 

Can you take a picture of it, and post it.

There are quite a few harness under the dash, and it could be:
ign ( which does not seem to match up, by what you posted ).
DTC
Trailer tow pigtail for the brake controller
ABS diagnostic connector.
Driver's side to pass side with the power window, PDL, and power mirror circuits, along with some interior lighting circuits.

 

If you look under the dash from the floor, it is the harness that runs on the bottom of the dash that is about 2" round. It runs right above the diagnostic port with the trailer brake plug taped to it. I believe the ignition, emergency brake and others branch out of this harness. Here are the 3 wires that I'm mainly looking for:
Orange
Light Blue with Orange Stripe
Purple with Orange Stripe

 

In order to find them, we actually need to know what function is involved first. The schematics are not oranized in any way by color.

If you state what you're trying to do, we can provide help.

I don't know what function they do. I was running a bypass switch this weekend and accidently cut those 3 wires and had to splice them back together. Everything seems to be working fine, just would like to know what to look out for if something starts acting up.

 

LOL
where in here is it? the green plug?

 

Your close. I put the bypass switch on the tab where the diagnostic port is mounted. Right above that is a 2" wiring harness. If you look at your picture, follow the wires to the main wiring harness(down), that is what I'm talking about.
So far so good. Everything on the truck is working fine. Even the **** bypass switch is working.
