Well, here is a pic from the alternator. The wires go into the wire harness and towards the firewall. I can follow it up to where it joins the main wire harness undere the hood on the firewall. Where it goes from there, who knows?
The wire from the battery goes directly to the starter (starter cable). There are some wires on the solenoid that, too, goes into the wire harness.
Without referring to a wire diagram, I am afraid that is all I can offer.
