Skip-shift, reverse lock-out, and I think even the speed sensor all plug in on the driver's side.
The tranny will function without anything plugged in, but you'll set codes for things like no speed sensor, or skip-shift disabled.

So if you arent getting a light, and the system isnt hooked up, Ide say just leave it alone. Mine is unplugged and the wiring is long gone.
