O/D light wiring diagram.

I have for awhile now wanted to do a floor shifter in the truck. and get rid of the column shifter. only problem is the OD light/switch. how does it work, is it just a momentary push botton and the PCM turns on the light??? also anyone know how many wires there are to the switch??

I can get a floor shifter with a push button on it, and then just put yet another /ubbthreads/images/graemlins/smirk.gif light on the dash for the OD off feature.
