If don't want to use the factory set-up, then do what the manual says for the GSS-300 says and use the relay. Mount your gear selector sensor on your 4L60E just like in the manual and adjust it. I would then wire the reverse lights to the terminal on the GS-3000 that says Reverse so the lights will come on when in reverse.

The current factory setup isnt working, which is why im asking the question. I would like to use the factory NSS/backup if possible. The difference is the factory NSS is setup for a 3 speed system and the 460le is not 3 speed.

I have tried to adjust the switch, but i can only adjust as follows:

park-starts
reverse-no start
neutral-no start
overdrive-starts
drive-starts
2nd-starts
1st-starts

All while the reverse lights never come on.

I have jumped the 2 green wires on the reverse switch and the reverse lights light up, so i know they work.
