Oooooooooohhhhh, I gotcha, I didn't know that the door activated wire was just basically a ground, and that you could have a on and off switch by having a body ground, (or in your case the light has a switch in it) Thank you so much for that info, I didn't have access to a fsm, I'm going to add that into the guide tomorrow!!! I really appreciate it!!!The FSM shows how the factory light fixture is wired (if installed) and that's how I wired it. The instructions that came with the Amazon were a little confusing, but I eventually figured it out. There's 2 wires in the OEM harness/connector. The blue wire is a constant +12v. The red wire is the door switch line. So if you wired your lights to the two wires in the OEM harness, you're right - you don't need to ground it. The hatch switch will turn it on and off. But if you have a 3 way switch on the fixture, you need a ground connection so the "on" position will turn on the light with the hatch closed - like if you were sleeping in it.
