Where does this plug in to???

[Ex President]

This is on the opposite end of my 3 prong "69 model" NSS wiring harness... Has just been sitting behind the back of the motor for some time now apparently. I figure it has something to do with my Reverse Lights, because they have never worked since i've owned the car. 

BTW: My car was originally a column shift car but is now shifted with a B&M Floor shifter...

Thanks!

On mine the reverse lights are from a connector on the bulkhead (engine side). Two wires ,connector is side by side and slightly slanted. A pic of your bulkhead may help. I don't have a connector like that at all,doesn't mean mine is correct.

looks like the 3 wires plug down the the auto trans , 2 black are the power in & out to the reverse lights & the brown grounds at the NSS switch in the trans preventing it from starting except in P & N

Yea, my schematic shows that the wire colors correspond to the reverse light circuit, but there's just no place for this to plug in to.

The wires on my schematic actually run straight into the bulk head in the C and D slot on the lower most plug... Problem is, those spots are already occupied by wires.

Mine is a 4 spd , that's why I haven't seen a plug like that. Where do the wires from the bulkhead go? Pic?
