you need to cut the plug off your old v/r and make 3 conections. connect the white and white, the white/black and the white/red, the black/white and the blue, and the external ground. Then your new alternator you just need to hook the sense and lamp wires up! to find what ones those were i just went to oriellys website and looked at the alternator i had, in the pictures they show what wires are on the plug for that alternator! mines from a 97 eclipse gst
