I have my reverse cam hooked up to my Kenwood DDX616 but now want to hook up the reverse sensing wire.

Does anyone know where to find it to tap into and also whay color is it?

Thanks in advance.

 

2010 ford f-150

Grey/brown at the reverse light relay in battery junction box.

The battery junction box is in the engine compartment, behind the radiator. On vehicles with auto-dimming interior mirror or rear view camera, can also use blue (+) in the passenger kick, harness to rear.
