Reverse lights come on with ignition

[Bigred1985]

OK, I'm new to this forum..I'm 18 years old I bought a project truck. 1985 Chevy k30 4wd SBC 355 with 700r4 Detroit locker rear end..But as soon as I turn my ignition to the on position my reverse lights come on..I have no wires on the NSS at the base of the column..And don't know alot about wiring and could really use some insight! Thanks! The pictures are from when I first got it home to it being almost done..But these small quirks such as the reverse lights are hindering me big time.

Sounds like someone may have bypassed the Neutral Safety Switch/Reverse Light Switch because it went bad if nothing's plugged into it. Do you see two wires spliced together under there? If so, you'll need to undo that, replace the switch for kicks, get the connector, and splice it on in. I'm guessing you can start in park and neutral because it has a mechanical lockout, but your reverse lights are really the only problem.
