Reverse Wire

[coolman1987us]

I Just put a set of aux. lights on my rollbar facing back and i want to wire it so that i can also have them come on when i put the truck in reverse. I already have the lights working on a relay with just a switch. Is there anywhere i can pick up a reverse signal from inside the cab +12v?

you need a three position (double throw) switch.

theres a wire that has 12+ power when your in reverse on the side of the trans. you need to splice into that wire and run it to one pole of the switch. output to your relay should be the center contact on the switch. 12v positive should be the second throw of the switch.

this will give you "on", "auto", and "off" modes for your lights.

i can doodle up a schematic if you need.

Ya i know how to wire it, i already got it all done. I ended up just running a wire from the reverse light up through the cab alongside the power wire for the lights.


The way i have it set up is with a SPDT switch and a relay. (on.off.auto)
My KC lights are set up the same way but on the high beams.
