I just picked up some power leather seats from an 07 Cobra to put in my non power seat 07 mustang -I've heard everything from " oh yeah it's all pre-wired from the factory", to "you have to buy a new dash wiring harness" - I just got the seats and haven't tore into the car yet, I'm hoping someone has some experience wirh this so I know what to expect... The only thing that really threw me for a loop is the harness and computer mounted under the non- power pasenger seat on the cobra seats. Also seams like there are alot of wires in the harness on the new drivers seat as well. Any clues?
