NSS / backup lights question

Wired up the purple and white to the Backup Light Switch and the ground on the starter relay to the NSS. Fired up the car and everything worked like a charm.

Not learned a little — learned a lot. I didn't remember a whole helluva lot from high school electronics but this was a good refresher. I also learned which connectors work the best when installing these kinds of things.

Thank you all for your help. I know I'm a slow learner but your guidance combined with seeing what's actually connected to what helped me big time. Thanks once again, so grateful for this forum. :) One step closer to getting the beast back on the road. :) :)
