I can't get a wiring diagram small enough to post here, but I can tell you there's nothing in the starter circuit to interrupt it via theft deterrent. It has the ignition switch, P/N safety switch, and a starter relay. The relay's coil is grounded on one side, energized on the other from the key through the P/N switch, and the switch is powered by Ign A fuse in the underhood fuse/relay panel. That's were the starter relay is too.
If you gimme an email address, I can email it to you, in .bmp.
