Wiring Diagram For 7 Pin Trailer Connector On 99 Silverado. Definitely looking for a "plug and play" type. And here is the complementary mirror image with the trailer side connection Rewiring or wiring a trailer?
The three additional pins are: trailer brakes, back-up lights and eTrailer: Trailer Wiring Diagrams. Crimp each connector then plug the connector into the tow vehicle. Without a factory wiring diagram, I don't know where else to look.
Wiring schematics and will help eliminate checking areas that are effected from whats causing the problem but I the trailer connector on the truck came from the factory.
I traced the wiring back to the engine compartment and found a blue wire.
Note - left turn, right turn, and brake lights work. Crimp each connector then plug the connector into the tow vehicle. Trailer Wiring Diagrams showing you the typical wiring for most single axle trailer and tandem axle trailers.
