Im putting a motor back into my 89 IROC and I cant remember where a couple wires go around the starter. I know that the purple goes to one of the smaller terminals and the red wires go to the big post, but what color wire goes to the knock sensor? there is a black wire and a white wire that I am not sure about.

 

I found a site with wiring diagrams. This might help. http://www.geocities.com/vtcamaro/Wire-Diagrams.html
