Kevin - I have the wiring diagram for my truck. Thanks.

Otto - I was looking for information on the ignition switch/key switch, but I'll save those pictures for my light switch install. Thanks.

Tomorrow morning I will test the key switch to see which terminal gets power from the battery. Right now I'm assuming it's the terminal with one wire. I'll update this thread with my findings.
