Hopefully, Randy will step in and say something. If not, e-mail or call him. He's at Fifth Avenue Auto in Clay Center, KS. He sells a handy booklet on conversion and a device called a DA plug to connect the alternator in without installing a new ignition circuit. There was a wiring diagram in the tech section which will help you. Wiring harnesses are okay, but as simple as these old trucks are, I just bought a few rolls of wire, some non-adhesive wrapping tape and some plastic alligator tube.
