I want to swap in some 9 way seats pending the ability to overcome seatbelt issue. Anyway, I took all of the wires when I got the seats and it seems as though each seat and the control panel all have their own power and ground. Where can I get power and can I run one wire or should I run each seperately? There is also one grey wire coming from a harness that connects at the drivers seat coming from the control that I have no idea where it goes. The seats work fine with all functions without it, but I hate to have a wire just hanging out there.
