None of this matters
I've used relays before to wire electric fans but I can't figure out what I'm doing wrong this time. I've tapped into the reverse circuit to trigger the relay and power and ground wires are coming up to the bottom of the opening there, they go directly to the battery. I've tried 2 different style relays I have around I can't get it to work. Trying to use the factory reverse lights as the trigger the relay and send power through to the auxiliary backup light.
