More info on why I'm asking. It's probably a CDO thing but...
since a few days ago, my brake light will turn on for a fixed amount of time
if...(and I think this is true) there's a
change in current flow EVEN WITH THE CAR OFF!!! For example the following
things cause the brake light to come on
for about 5 seconds and then turn off (with the car off):
* hitting the horn (sometimes)
* turning ON the lights
* turning OFF the lights
* opening a door with a couple of accessory lights on (sometimes)
What the heck???? I looked under the driver's seat for any loose wires near
the handbrake wire connector thing and couldn't find the handbrake wire. I
disconnected mine a couple of years ago since the connector had failed. I did
find a loose wire under there but grounding this one
caused the Fasten Seat Belt light to turn on, so I knew it wasn't this one.
Could it be the seat belt buzzer thing under the dash? I have disconnected the
grounding connector under the steering column because
the buzzer was enemic and horrible sounding.
Oh, also when driving, the Brake light will flicker sometimes and do the 5
seconds pulsing at other random times during a drive...
Goblins?
Please help.

The seatbelt warning light is controlled by the
time/buzzer module on the interior bulkhead.
The light & buzzer will operate (momentarily)
only if the seatbelt is not fastened when you
first crank the car.
FWIW the timer/buzzer is easily disconnected.
Assuming the handbrake is OFF, the brake
warning light illuminates while the key is
in the "crank" position to provide a lamp
test. There's no timer here. Of course the
lamp should also light if the handbrake is
on, or if the PDWA sense hydraulic problems.
Hope this helps,
