Traile Wiring question
On the second factory trailer wireing plug in the rear of the truck there are 3 wires. (the plug for a 7 pin RV connection)
Orange, blue, and black with a stripe.
Im assuming....
Blue=trailer brakes
Orange= Auxilary power
Black= Reverse lights?
Can anyone confirm this?

I don't know if you still need the info...
From the 1994 EVTM, it shows:
Dark Blue as trailer brake feed
Orange as trailer battery charge
Red with Yellow as trailer backup lamps
At least for 1994, I don't see a black-colored wire in the circuits going to the trailering connectors in the rear.
