I am putting the finishing touches on my new Hurst shifter (swapped from a manual), and I have to hook up both of these switches.....from scratch. I don't have any old wiring or switches exisiting.

The reverse lights: I found the light green wire under the sill plate that goes to the reverse lights. It looks like 12V switched power and green to the switch.

Neutral safety: Do I just take the purple wire at the starter and run it through the neutral safety switch?

Thanks for any help.

Yes....the purple wire goes from the ignition switch to the N/S switch and then to the starter.
