Can anyone identify this plug???

Going back together on a full tub and trans swap. This is a 2004 TJ with it's original 2004 dash harness. Jeep used to be an automatic... now swapped to manual. Wouldn't you know it... this is the only plug I didn't label. It's coming out of the dash harness right next to the airbag module in front of the shifter, under the hvac. This section of the harness runs down the inside of the firewall to the right of the steering column... this is the second to last plug on this section, followed by the yellow airbag plug which terminates this section of harness. My guess would be maybe it plugged into the shifter assembly when the Jeep was an automatic? Due to it's length and location, it must plug into something right in that vicinity. Can anyone help identify? Thanks!

Looking at a 2005 TJ wiring schematic - looks like something to do with the HVAC controls, though I can't match the wire colors

Thanks Mickey. HVAC gets it's power from the big green plug on pass side... so I don't think it's HVAC related. But... I just looked at a '97 model and next to the airbag module, there is another smaller module with a plug (see pic). This apparently is a G sensor for the airbag. So, maybe this is an outdated/unused connector for the later models (hence why maybe I never labeled it). Still not 100% sure though. I'm not sure / don't recall if this additional module exists on the later models. Wire colors are same by the way. Photo is sideways, sorry.

Possibly G-Switch (wire colors: tan/white, yellow/violet, pink/orange). Only thing I can find that's close.

Thanks Jek... I researched further, and it is indeed a G sensor that works with the older model airbag module. I think the later model TJs have the G sensor built into the airbag module... thus rendering that mystery plug useless. I don't recall removing a G sensor from my 2004, thus why I guess I never labeled the plug :-)
