its been a long time since we finished and figured out the problem. so i'm sorry i dont recall what it was. he figured it out one day while i wasnt around and i dont remember what it was. i do remember that there are some wires that go to a little plastic box on the fender. i think its just a place for ground wires to hook up. he had some of the wrong wires hooked up there and when he fixed that it ran alot better. so i'm sorry i cant be of much help!
