[V8] Interior light timer

[Roger M. Woodbury]

The overhead and footwell lights in my V8 do not work when the door is opened. The overhead light works when turned on and off by switch only.  The warning buzzer sounds when the door is opened and shuts off when closed, so the door jamb switch works.  

The footwell and overhead delay circuit is apparantely faulty, and I assume this is a relay.  I wonder if anyone out there knows WHICH one it is? Anyone with a BTDT?

Thanks,

Roger

P.S.  My V8 is on the way to the shop today for its first step in the restoration.  Nose job is next.
