Default 1968 Ignition Switch wiring diagram

I pulled my ignition switch out on my 1968 and now having difficulty figuring out which wire goes where. I thought I had marked each one when I pull it off, but when I put it back together, now the starter will not engage.

Does anyone have a color keyed wiring diagram of which wire goes to which terminal?

Thanks

Did you get this figured out yet ? I have a good but I can't copy or send it to you otherwise I might get my rear in trouble with the maker.
I can make a drawing by hand if you need it or I can send by clock location. Most of those switches had written on them which wire went to what terminal.

I can only offer this and then check to see if my old harness still has the connector. If it does I'll let you know what color wire goes to each position.

I labeled only the ones that were in the shadows.

Pictures are easy.

I've saved your wiring legend and want to thank you Roger, you seem to be the go-to guy when there are wires involved.

I’m installing an A/C in my 68 C3. Your answer in this thread is very helpful. Thanks,
