GM Universal remote extra button? Answered
I have a GMC pickup with a 3 button remote. I discovered that GM uses the same PCB for all its remotes, so I have a 3 button case surrounding a 4 button PCB. I want to use the extra button to control an add-on to the truck. Does anyone know of a way to acquire the RF receiver, what the part number is, etc, and how it would need to be wired in to allow control of external lights on the truck? I know it would have to be wired into a relay to allow the kind of amperage I am thinking of...but what else am I missing?
