neutral safty switch?
Anyone know which wire I'd need to tap into to wire in acessory back up lights if I want them to come on in place of the stock ones? They haven't worked since I bought the truck and I've got new bulbs and I have a new pin on the column. I think a wire got cut by the PO

Have you actually tested the back up sockets? 99% of lights not working is grounds. Time to get yourself a multimeter and trace that wire if they aren't working after cleaning the grounds and testing. I'd be a little worried about a hot wire loose under the cab or the dash.

The rear ground is in behind the twilight housing. I have a manual so I am unsure if the NSS grounds or not. I basically have a hot from in the cab to the switch in the tranny then to the harness that goes to the rear.
