Big Mistake - Need Electronics Help

[Boomer73]

Ok, so I went and did something not so smart.

In the process of installing an overhead monitor, I had to relocate the rear audio controls. The trim that was supplied with the monitor made provision for the control relocation. Only problem is, the factory harness wasn't quite long enough to get it to the new spot - like 3" too short. So I figured I'd cut the plug off the harness and make an extension. It was AFTER I cut the plug off that I realized the wire aren't UNIQUELY color coded.

So now I have 15 wires hanging out of my ceiling and really no idea of what they match up to on the plug since there are 2 - 4 of each color.

Does anyone have a wiring diagram of this plug? Ideally something that tells me what color and voltage goes to what pin on the plug? For example, I can probe a white and get 12v and probe the other white and get 5v but have no idea which pin they're supposed to go on in the plug.

HELP. SOMEONE...

With the help or a wiring diagram from the dealer, I finished the extension harness and fixed this problem. I will post a scan of the diagram and some photos of the harness I made when I return from vacation.

Here's the wiring diagram...

My splice work. Soldered joints and covered with heat shrink tubing...

Finished and all wrapped up with electrical tape (thats it on the right). In the end the plug was extended about 8 inches...
