I wanted them to power on independently but also turn off with the headlights so I wired the power for the relay through the gauge backlight power wire. Got some 880 bulb connectors, a hella headlight relay, and a squaredash cargo lamp switch from the junkyard. Also got a dorman relay holder and some wire from the store. Not sure how they are supposed to function from factory but they work like fog lights in every other car I've driven now.
