I have a 3800 series 2 out of a Buick regal GS that didn’t come with a neutral safety switch connected to the wiring harness, but the switch is on the transmission. How would I add the wiring to my harness?

Yep, I got you covered, here is the gear range sensor (neutral safety switch) wiring so you can make it happen! Check out the images (below). Let us know if you need anything else.
