77 interior light timer
 

Anyone had to replace interior light delay timer on 77? have heard they are hard to find replacement??

If you already have the wiring there for the timer Willcox Corvette sells a electronic direct replacement.

Not sure what the delay time is set for.
There are a few NOS GM #491294 delay timers on e-bay now $$$
If mine were ever to go out I would replace it with a electronic unit.

Thanks!

You can bypass it by connecting the white wires together. The connecter separates to do this.
