It's a 1980 El Camino and it had HEI but the Olds V8 required a new Distributor and Starter. I see the giant red wire from the + battery, a small diameter black wire with a large eyelet, and a red wire with fusible links. I assume they all go on the large pole. From the wiring diagram, it looks like there is a purple wire to the distributor....purple being lavender. If that is the case I will have to splice in a connector as that one is cracked and missing a piece of plastic. The ground wire from the - battery terminal grounds to WHERE? I just want to make sure I don't start a wire meltdown when I connect the battery or turn on the ignition. The small terminals on my starter are R and S. Someone please give this old 12 volt idiot a primer that even I can understand. Pictures are sooooo much better than schematics 🤪
