I am planning on adding aftermarket A/C to my car and a previous owner already upgraded the radio, so I was going to get a 100 amp alternator for my car. The 100 amp though is a one wire alternator and I wasn't sure how it would hook up as there are three wires connected on the stock one. It is listed as fitting this make and model of vehicle (a 1976 pinto with 2.3L). Any thoughts?
