The Bel Air hardtop is not included in the wiring diagram. has no roof dome light but rather a light on each side at lower window level between the quarter window and back glass.
Basically it would need a hot wire running from the headlight switch to each of the lights. Then a ground wire from each door jamb switch and from the rear arm rest manual switch to each light. All the switches do is complete the circuit by grounding it. The lights are hot all the time.
