Question on starter wiring..... pls help!!

Im rebuilding my 1972 Cevelle, I need help rewiring my starter. There are 4 wires currently going nowhere. I need to know which wires go to the starter...... the colors of the four wires are black, red, orange and purple. I know the red wire goes to the battery but dont know about the other three, if somene could help me out with this or direct to me to some online wiring schematics I would greatly appreciate it!

I'm guessing by now you have already gotten you're answer on the starter wiring problem by now. If not I can direct you to a website if I can find it again or I may be able to scan in the build manual page that goes for the 72. I purchased the build manual from either Danchuck or OPG. It has helped me on a number of occasions during the rebuild of mine.
