Chevelle starter wiring

Would anyone have a diagram for a 72 Chevelle/elCamino. I have to rewire the starer and have a red, purple yellow and black wire running down to the starter. The purple is for cranking ( I remember this from my alarm installation days). The red is constant power. The yellow should be for 12 volt to the coil when cranking and the black I would guess is a ground.

Can someone confirm the yellow and black? I dont want to ground a wire that carries power or the smoke will get out of the wiring harness and I know that if the smoke gets out, the wires don't work any more.

I don't know if this will help, but I can confirm the wire colors from a 1972 Chevy full size pickup wiring diagram: purple from the ignition circuit to the S terminal, yellow from the R terminal to the coil + terminal. And of course the battery cable to the B terminal.

The black wire you mention I am not sure about. Best thing to do is trace everything out with a multimeter. Then you won't have any surprises.

If I'm not mistaken, the smaller black wire had a big teminal end on it, and it went to the big main power lug along with the battery cable.
