I am installing the wiring harness in the engine compartment ('68) that includes the purple and yellow starter wires. My engine is a chevy 350 with an Ultima 03-0485 starter. This starter is not marked with any "S" or "R". Trying to figure out which wire go where (see photo of starter). I am assuming that the positive battery lead goes on the big terminal at the bottom. The purple wire would then go to the smaller terminal at the upper left. Do I ignore the yellow wire and just tape up the end?
