If I understand your question, I think you are talking about the fiberoptic cable. It plugs into the ashtray housing and goes to the back of the gauge cluster, in the upper right hand corner when you are sitting in the truck. That's how my 82 is anyway.

It transfers light from your instrument panel through the cable to illuminate the ashtray. If you have it apart shine a flashlight in one end and see what comes out the other.
