Going to be hauling a car dolly that has 7 pin connection which plugs into RV, if I'm also using magnetic lights on back of car..how do I also plug this into RV? Hope its simple.

Does the car dolly have lights? if it does your going to have to tap into them. Since this a car dolly it most likely has provisions for this.

Dolly does have lights, would car also require lights?
