Do yours work? Also after looking at the 7 pin wiring diagram here in the documents section it doesnt seem to have a wire for reverse unless for some reason it is [b]Auxilary wire.
The reverse lights are wired up through the "Auxilary" pin, #7, the big round center pin.
haven't been equipped with reverse lights until just recently.
I hooked mine up myself to make mine work. I had to tap into the reverse light
wire at the lighting
connector inside the left rear quarter panel of my minivan to activate the proper connector pin on my tow vehicle's back bumper.
