Does anyone know the Colors and schematic for the 7 Pin Trailer harness? I will update this post as I receive info. I'm looking for the 2nd Gen Vehicle side as trailers color can change. Also are all these active with the OEM harness?

This is looking directly at the Male End on the vehicle.

1:Blue = Ignition Power
2:Green = Right Blinker/Brake Light
3:Red = Brake (brake controller)
4:White = Ground
5:Yellow = Left Blinker/Brake Light
6:Brown = Running Lights (fog)
7:Black = Reverse Lights

I went out and tested some of them. What I'm looking for.

1: This turns on with the ignition. Is this Aux power for charging a trailer battery?

Color for wire for each one.

Prime,

I think the last one you posted is correct for wire layout. When I put the X in reverse the center one go power.

I would like to verify color but it is not needed for what I'm doing.

I'm thinking: The following are guesses
White = Ground (size of wire kinda gives it away)
Blue = Brakes for trailer (seems standard might be wrong)
Red = Ignition Power (it is the other large wire, just makes sense)
Green = No Idea and I'm guessing at the color as I'm color blind
Yellow = No Idea and I'm guessing at the color as I'm color blind
Orange = No Idea and I'm guessing at the color as I'm color blind

So here are some pictures of the harness and the wires.

Derrick, this is what I got when I tested mine out to replace my plug:

FYI, the color coding on the wires is as follows (as per FSM wiring diagram and double checked by me with multimeter; I'm 100% certain of these):
RED: Electric brake
BLUE: Auxiliary battery power
GREEN: Right turn/stop lamp
YELLOW: Left turn/stop lamp
BROWN: Tail lamps
WHITE: Ground
Black: Reverse lights
