I really only have issues with the front section infront of the manifold. It goes from the alternator across to the cooling fan etc...
I can handle an install as long as don't have to start pulling stuff off the car to do it. Ford dealership said I would have to remove the radiator and some other things as well. The also said that it would cost $275 for the harness. Ofcourse that is the entire thing. I think it was around $850 installed.
Where did you get yours?
As for the paper clip I don't know how to do that
