PDFs of the GM squarebody wiring and service manuals are in my signature.

This is a fair representation of a GM dome light circuit.

RTFM... GM Parts Books, GM Schematics, GM service manuals, and GM training materials...Please include at least the year and model in your threads. It'll be easier to answer your questions.
And please let us know if and how your repairs were successful.
