I put this under the Technical section too so be patient with me because I am in a relal jam.
When I took the engine out of my truck I was in a real hurry and did not pay attention to the wires I took off of the starter. I thought surely a book would tell me exactly how to re-wire it. NOT SO. Every schematic and post I have found here has not helped. So- the 10 gauge red with large hole connector obviously goes to the large post in the middle. I have two other wires. One is 16 gauge and using a continuity tester I found it goes to the instrument cluster lighting. This wire is so dirty and old I can't tell the color. May be purple or brown. The other wire is 12 or 14 gauge and brown. I have HEI ignition and a guy told me to forget about the brown or purple and connect the 12 or 14 ga to the block side small post. I really think the 3rd wire (16 ga)was connected to one of the small posts but not sure which one. If you have a definitive schematic, send it. Otherwise, I really need to know where the wire 16 ga wire I mentioned above that goes to the instument cluster connects. It must connect to the small post on the frame side or the block side. Like a dummy, I think I cut that wire so it has no connector on the end to tell me if it was to connect to a small or large post. What is odd is that the wire is cut but no connector is on any post. Not sure what I did. It could be this wire was for a coil in the past but have no idea. Help !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
