Half of them have been replaced with some BC's from NAPA, the origionals were broken and stuck on GP's when I swaped my motor. Both harnesses I had were in pretty bad shape. Made due with what I had at the time, but now Id like to have everything working right for once. Had bought a new GP controller a while back and it just made clicking noises and never heated, then after re-hooking it up and moving the ground wire around about 8 times, fixing rub spots on Gp harness and lots of cussin, the damn thing started working flawlessly for about 2 weeks then quit all together. Napa gave me a new one and its back to the click, click, click no heat crap. Think my harness is just shot, its the only thing I can figure.
