I recently did a whole truck wiring LS conversion on my 65 C10. I'm just as intimidated by wiring as you are. One step at a time. Divide it in sections. Make notes. Tape and mark the wires as you go so you can go back and remember what you did and what for. You can remove the tape after. I had a lot of unneeded circuits in my fuse box I was able to borrow for other things.

I do not have that brake switch. I've seen it before, but for some reason I thought it was required only for cruise control. I had no idea I needed that design for my swap. Thank you so much for sharing. Now where do I get one like that?

Thanks for the vote of confidence for the wiring. I've started taping some of the leads. I'm sure I'll have some questions for you guys along the way.
