Tkx., no need to double check anything unless you really want to know more.
My babe is a 1997 GX-R
FZJ80L- GCMNUV
VIN : JTB11UJ83V5013283
Trans : H151F
Axle : K294
Mileage : 688, 550 Km (single owner), I hope I can reach 1M km's in my lifetime. According to my calculations I still need to keep driving for the next 13 years , i.e. till I turn 77

doing at least 23K Km/yr, otherwise my daughter will do that milestone.
I have no key illumination light, no sun/moon roof, no auto-central lock (manual center lock only), no automatic headlight thingy, no cruise control, no vanity light, no diff lock, no OBD, etc.
I can lock the truck from the outside with key in igntion & with engine running also.
Driving as is for a few days now and everything running well, headlights, turn signals, brake lights, hazard, cabin lights, reverse light, etc.
The buzzers for 120 Km/hr, seat belts & key in ignition were disconnected a week after I bought her.
I do not have the exact FSM for my model, but have used various FSM's for different models over the years.
I did a search on some FSM's on the resources portal and managed to dig out the following :
I'm under the impression that this switch is part of the standard harness the comes with all steering wheels for various models, I guess it makes sense (more economical) during manufacturing & assembly of steering columns. Whatever is connected to that switch depends on the options/accessories avaialble in any partciular model.
The collective intellgence of this group is a treasure, thanks to all.
