Need help with a dash harness plug

[blackgn1]

Installing my refurbished dash. Got everything installed except for one plug. It has a black and grey wire and is in the glovebox latch area. Cant find any loose connectors to plug into.

Possibly for the illuminated trim plate. Gray is typically a dimmer voltage wire with the other being a ground. See if the voltage on the gray wire varies as the dimmer switch is rotated. If so, it may be that, or it may go to the HVAC head.

That Gray actually looks white to me which would make it C367 and it is for the sentinel photocell. My car doesn't have twilight sentinel and has the same plug in the location you are at just wire tied up. White and Black.
