Re: 68 C10 Yellow wire from firewall to starter/coil.

Now I am confused because the stock diagram from post 2 on this thread shows purple coming out of the FW block, getting resistance and heading to the coil on Yellow. I am yellow at the coil but on my FW block that same position has a red wire coming out. I can put a volt meter on it and check for voltage at ACC and run position, but I dont want to rob that wire from another system that needs it (although I am not sure what that would be)
