Ok... my mechanic has had my car for several weeks now trying to find time to throw my NOS 5171 in. I have a beater car and the weather has been crappy, so I really didn't care and told him to take his time. Anyway I've read on here that the total install time is roughly 3-4 hours on the kit. I talked to him today and he told me 2 things. First, he said it has taken him WAY over the estimated time, more like 10 hours. Second, he says the harness that came with the kit doesn't fit into the factory harness or whatever and that he's been on the phone with NOS for 2 days trying to figure out what to do. They keep telling him to just hack into the factory harness and he doesn't really want to go doing that. So, two questions. First, has anyone had a wiring harness related problem with the NOS 5171 in a '97 Cobra? Second, whats the deal with his long install time? I've been going to him for several years and he's always been very honest and does great work - he kind of specializes in American performance stuff so I don't see why he would BS me... what do you guys think?
