'74 starter wiring ????'s

[Jonboy]

What wires go to the "R" terminal on the starter? I know that the purple/white starter trigger goes to the "S" terminal, but dos anything go to "R"? I could have sworn there were two wires coning from the "R" terminal, but I cannot get the truck to start. It is acting like the neutral safety switch is not working, and I have checked it all with a test light. It seems good. There is a pink wire that is routed there and goes to the back of the fuse box that is getting very hot with the key on, too. Any ideas? I really need to get this running this week. Help!!!!
