Mine is just wired to the upfitter switches in the cab right now. I'll have it on both if possible. Like you say, if the truck is locked you can't turn them off but that's almost what I want. I wan them to turn on and off when the truck is locked, same as the headlights. Very often I have something in the back I need to get and don't want to turn them on, get it out, turn them off. Just be best to have them automatic.
I guess what I'm trying to say is they will be on the dome circuit with the aux switch as a permanent on override
