Who thinks they can figure this out?
Floor-mounted shifter column for 4x4 has two lights. One to illuminate when park lamps come on and one to illuminate when 4x4 is engaged and ready to go. The bulb for 4x4 engagement is not illuminating. My floor display's front axle does not light up. It used to though. 4x4 Works powerfully. 4LO and 4HI both engage just fine. Bulb is OK. Socket is OK.
Question is, what sends voltage to the tiny bulb to light up the front axle icon? Something mounted on Xcase or front diff? I can't tell because the wires run underneath my carpet. I do know that the bulb socket uses a black and a white wire. Where the hell do they come from? I have a test light and meter if anyone can tackle this one they would really make my day.
Truck info; 1990, k1500, 350TBI, 700R4(rebuilt), Electric actuator, Floor shifter, Single cab, Fleetside, Shortbed, NP241 Xcase
