Piece of cake, no surprises. Replace the silly little short relay clutch cable with a Ford Motorsports one, it will save your friend a pile of grief later on. It seems like the factory relay cable is made of cheese and break on a regular basis if the car is speed shifted, the Motorsports one is actual high strength aircraft cable. Definetly not one of Fords better ideas.
