After market column wiring diagram

I recently purchased a '71 C25 that has an aftermarket steering column in it. I'm pretty sure it's the one that LMC sell. Does anyone have the wiring diagram for it? I contacted LMC, but they weren't helpful.....

Thanks in advance!

Most aftermarket steering columns employ a standard GM turn signal switch.
You should be able to use a GM truck wiring diagram for your year model. These diagrams are available as a free download on the ELECTRICAL forum on this site.

Does it have a straight GM plug?

Re: After market column wiring diagram

Thanks for posting this!! I hadn't started troubleshooting anything yet when I posted the question. I don't like to start troubleshooting without a schematic.
