Reverse lights help

Hey guys, I've got a 68' GMC 1500, I swapped the TH400 with a 700R4 out of an 89' chevy van. I got everything mounted and my Trans linkage hooked up...then realized..NO REVERSE LIGHTS!! One of those Homer Simpson moments, "DOHH!!!". Where's the Neutral Safety switch located? What do I need to do in order for them to work?

-The truck is missing the gear/needle indicator on the column, so I can only look at the hole and count the gears as I move the column shifter.

Thanks in advance

Re: Reverse lights help

The NSS is located on the top of the steering column down by the brake pedal.
It has 4 terminals on it, two for the starter and two for the reverse lights. The reverse lights are green.

Re: Reverse lights help

Thanks for the picture, helped a lot. Which wire on the starter acts as the ignition wire? The engine is a 2004 5.3l. The starter has only 2 usable posts, compared to the old starter which had 3.
The old wiring diagram shows a purple NSS wire, and an orange and purple wire which is not labeled. Should I put both wires on the same post?
