Lights Warning Buzzer on '81
The audible noise for my headlights no longer works. When I turned the car off and the lights were on it would emit a sound. Not anymore. What do I need to replace and where is it?

The warning buzzer is a black box attached to the right side of the fuse box below the steering wheel.
There is only one buzzer. Are ALL of the warnings out? Key-in with door open? Fasten seatbelt reminder? If not verify that all of the connections to the buzzer module are secure and clean.
Replacement buzzers do not appear to be available.

At 6'3", 250# I feel for ya. There's not much room down there for any but little people though 
The module gets its power to buzz from the STOP/HAZARD fuse so do be certain you have brake and hazard lights.
The module plugs plugs into and locks into a connector at the rear. There's also another connector at the side plus another wire or two that plug into the front of the fuse box.
The orange wire in the side connector should have constant +12V from the STOP/HAZ fuse
The light green wire in the side connector is grounded with BOTH the driver door open AND key in the ignition switch. Otherwise it is open.
The yellow wire in the rear connector is the power feed to the seatbelt warning light.
The pink wire in the rear connector leads to the GAUGES fuse and should only have power with the ignition switch at "RUN"
One of the black wires in the rear connector should always show continuity to ground.
The other black wire in the rear connector should will be grounded with the driver seat belt fastened and open with it unfastened.
The odd wire coming out of the module that plugs into the fuse box (at least it's like that in my '79) goes hot with the headlight switch on.
