I wanna hook up some of those door switches on my CJ7 like they have on the wranglers (open doors, lights come on, close doors, lights go off). What would be involved in hooking these up? I think they are grounds, so looks like I could buy a couple wrangler switches and mount them, but what about the wiring. I can wire them up to work with the headlight switch, but how do I rig them up where they come on with that switch in the off position (so i can turn the lights on when the doors are closed)? I'm sure I'm overlooking something really simple here, but I'd appreciate any help......
