Does anyone know how to hook up a reverse light.[img]i/expressions/face-icon-small-disgusted.gif[/img]

 

I would run it into the wiring for the reverse indicator. So everytimne you put it inreverse and the indidcator comes on the rverse light will come on...

 

That circuit would work. But to be on the safe side you should put a relay in the circuit so that the switch that turns the light on will not be overloaded. I think you might be better off just wiring in with a external switch somewhere.
