Here's a potentially dumb question.  

Is it possible to swap in the open-door 280zx doorbell buzzer into a 280z?

Why not... It's just electricity. If you understand both circuits you can make it work.

The Z switch is just a two wire switch.  Power on one side and ground on the other.  I converted mine in to a "headlights still on" warning buzzer.

I would need to use the zx relay in combination with the zx door buzzer im guessing?

Here's a thread with some stuff that might help.
