My engine wiring harness burned up a couple wires yesterday!
I think I understand now, you had to extend wires on a V8 harness to fit your slant 6?
Yes.
I got the old harness out yesterday and got the new one mostly all in place. Just have to install the new coil, and pick up the starter and alternator and get them back in, then I can start it up and see how it goes. It sure was nice working with new wire that can flex and move and isn't all hard and stiff and greasy. All my extensions were long enough. The temp sensor got a 15 inch piece of wire spliced in, and to my surprise, that was just long enough. It has some slack in the wire, so nothing is pulled tight, but I thought it'd be longer.
I'm also going to put in a new wire to activate the A/C clutch. For some reason, the factory wire was partly replaced, but the original piece that is there goes forward past the fuel vapor canister, through the hole in the radiator support towards the front marker light, then the first wire ends and a second wire connects to it, then it comes back through the radiator support and on to the A/C clutch.
And I'll leave it unplugged for now, as the old A/C system is low on refrigerant and there's no point charging it up or converting it to R-134 until I replace the heater core and maybe the A/C evaporator. Don't want the A/C clutch accidentally getting turned on and running with an unknown amount of refrigerant / oil in the system. It is all OLD.
