My replacement starter is a little different than my Delco Remy. There is an S terminal and an R terminal and the positive post. I don’t think there was a wire to the R terminal on the Delco. (Blue paint on it) What is the R terminal used for?

Hi John. Wow. This question is a hornets nest. Ask five people and get five different answers. The S is the wire to the switch. The R. If used is for bypassing the resistor during cranking. Do you have a 337 Q wire diagram? I do not. We should look at that to see if you have one wire or two. If you have only one, use the S terminal. Just remember the R will be hot during cranking.
Ok John. I looked at the resources section and found a Q wiring diagram. The original had one terminal. There should be a tan 14 ga wire from the solenoid to the ignition switch. This would be the S terminal. Hope this helps.
Thanks for the answer on the R terminal. Makes sense why it is not used on my setup…. Electronic ignitions!
