Does anyone know where I can find the reverse wire in a 09 inside the cab, all the other threads are for the 08 and I think the color/location may be different.

 

Wow, that vehicle (according to my tech sheets) is very different wire wise.

Reverse - Grey/Brown (+) @ Reverse relay at the Battery Junction Box in the engine compartment. *Note: Vehicles with the auto-dimming rear mirror or equipped with the Rear cam, you can use the Blue (+) in the passenger side harness to rear.

 

Thanks you are correct, I found it after tracing the wires all the way to the front.

 

Can you tell me where to find the passenger side harness to rear where the blue wire is located? Is it under the carpet or under the truck?

Thanks.
