I am putting a rebuilt 383 in my 74. I have replaced the old wiring harness to the starter. I am using a new gear reduction starter and have it hooked up so that it energizes properly. It only has one small terminal whereas my old starter had two small terminals.
My problem is that I have an extra wire in the harness that I can't figure out. The battery lead and the power lead are on the large terminal and the solenoid lead is on the small terminal. My schematics of the system aren't any help to try to identify the extra wire. Is the fourth lead the extra solenoid lead and therefore it is not needed with this new starter? Any electrical experts out there who can help?
Thanks ,
Bob
