The PO installed some kind of aftermarket starter which I am replacing. Picked up a stock style starter but am having trouble figuring out the wiring. I have a shop manual for the 74 Blazer but for some reason the wiring diagram is only for a six cylinder. I have a 76 Blazer wiring diagram but it has some differences it seems. Here is what I have: Two thick red wires that join into one that come from the junction block and somwhere else One black thick wire comes from ? One brown wire that comes from the firewall wiring block One yellow wire that runs back to the HEI distributor The battery cable that comes from the battery. Obviously the battery cable hooks up to the large copper post. There are two other small posts, one labeled with an S and one labeled with an R. Where does everything go? /forums/images/graemlins/dunno.gif Clearly I am a complete simpleton when it comes to electrical.
