Jerry, true the radio is hooked to the house batteries but the switch box harness is switched with the ignition. If you turn on the radio you can't get a video feed until the ignition is on. After giving it some thought, and figuring how easy the switchbox harness is to get to, I think I'll get power from there. I'm not going to use the trigger wires because of the three I prefer the rear camera, plus being able to see all at the same time on the quad view. If I used a single input monitor then I would use the triggers, maybe.
