So I'm putting an American Autowire Power Plus 20 circuit wire harness in my '77 C15. Getting ready to run ignition wires. Which terminals on the NSS switch are for neutral safety switch and which are back up wires? Also which are feed in and out?

Also, for some weird reason this harness has no wires for backup lights. I can run a wire from the output side of the switch to the back with the tail light harness, but what do I use on the input side of switch? Imagine I can just grab an ignition feed wire?

Looking for confirmation, but just found a video that shows the terminals closer to the column are the back up lights. Looks like passenger side terminal is light green so that must run to the lights and drivers side terminal must be ignition power in.

Thanks for the help. Didn't even realize wiring diagrams were on here. That'll be a big help.
