It's getting even better, lol. The PO had "wired in" a few things, over the years. Extra in-cab light over front seat off of a line on the light switch harness. He ran the power for the wench on his wrecker boom by coming off the starter relay to a second relay for power, and running a wire to the second relay. While unwrapping more of the harness in the cab today, and chasing down the wires I cut from his emergency lights and flashers for the wrecker boom, I found how he powered them. Off the power wire to the ignition, it appears. This has been hot enough that I don't think I can get them apart without destroying the plastic connector. I think this needs replacing. Looks like RockAuto might have it

Anyone have another source for this ignition switch harness?
