Are you reffering to the map lights?
dittoThis is a picture of the connector behind the driver side seat belt retractor. This is a common area of problems. On mine, the wires had corroded and fell out of the connector. These wires go to the dome light.
That's how I fixed my dome light issue in my 80 never bothered with the connector.in the mean time, you could use a crimp on set of connectors. that is how i did it.
