So, in the same vein, I have a factory camera system with a dedicated power switch and a rocker on/off switch. This switch actually controls power to two cameras, one in the garage and one above the ramp door which I use as a didicated rear view while traveling. I have a checklist item to make sure to turn this switch on before traveling and usually remember but frequently forget to turn it off after unhitching. Utilizing a relay to control this circuit from the running lights instead of or in addition to the rocker switch would make life a lot easier. Any idea what type of relay might do the trick for this? I'd also have to find a place to tap in to the running light from inside the garage if possible since the dedicated wiring and rocker switch are located there.
