is it even possible to connect them wrong? because isnt it just one wire to one wire i dont see how one canm connect it wrong.. (loose maybe but wrong no idea) please instruct thanks for your help
I mean either your +12 constant isn't connected to an actual constant +12 line from the car, or the ground isn't connected to a good ground point. Things like your illumination wire from the car will function as a ground, until you turn on the lights. Then lo and behold, it becomes a +12 line. I'm saying you wired the ehad unit to the wrong wires in the car.
