Tilt column light hook up?

[custom10nut]

This question is about my tilt column that I put in my truck.
Where does the little gray wire for the gear indicator hook up?
I know the fiber optic wire hooked to the back of one of the panel lights, but that won't power the bulb in the tilt column.
Am I doing something wrong, or do I just hook it up to a power source controlled by the light switch?
I'm sure there is a right place to hook it up.
