I'm planning to try and wire my T on my lonesome. With the help of some very good schematics from a member of the NTBA, KoalaT. In his drawing, the starter solenoid has 3 connections on it, "BATT", "R" and "S". However, my starter solenoid only has "BATT" and "S". Why is that and how will I hook it up to the switch? My engine is a 1984 305 SBC and the starter is for that engine. Anyone have any ideas?
