The gear position indicator light is in the same circuit as the light for the other dashboard controls, such as the radio, hazard switch, and HVAC controls.
One side of the light will have battery voltage on it when the key is at ON and the headlight switch is turned to either of the two "ON" positions; the other (low) side goes to the illumination control module, as you noted. All the low sides of the control knob bulbs are tied together and there's one line back to the module.
Are all the other dash control lights working properly?
Does your car have seat heaters? If so, do the seat heater switches light up when the headlight switch is turned on? Same for the remote control mirror control.
If neither pin of the two pin connector to the gear lever position light has battery voltage when the key is at On and the headlight switch is turned on, check the fuses in the cabin fuse panel. There's one that powers the gear indicator light, the seat heater switches and the mirror control.
Edit: Looked at the photo -- the seat heater switches are lit up. So the fuse is good. Back to the beginning . . . If there isn't battery voltage on at least one of the two pins on the gear lever position light socket when the rest of the lights are on, then perhaps there's a break in the wire going back to the common power source.
