Thanks. The siren only chirps when unlocking & locking. Otherwise its quiet (even in panic mode). But it is better than the peizo which cannot be heard 5 feet from the car.

I also took the advice from Chris. Replaced the dome lights, reading lamp, and trunk lights with LEDs ! ! They look great and Zenon White is very bright. These were cheaper prices and shipping (about $30):

The LEDs took about a week to arrive from Hong Kong.

The relays are wired up for the "Radio ON til Door Open" mod. Planning to install next weekend. After over 12 years, this car is finally getting some actual creature comforts.
