I just got a 1995 Mustang GT and went right to work on my least
favorite new car project: Finding and properly "adjusting" the
stupid door chime. In the good old days you could just yank the
wire or shoot the thing. Now they've gone ahead and included the
headlight alert so you feel ripped off if you just disconnect the
module and really, really stupid when you leave the lights on.
Have no fear however, a little time under the dash with clip leads
and a multitester always pays off. It's amazing that something as
simple as the door chime has over eight leads!
This should apply to the 1994 and 1995 Mustangs and many other new
Ford vehicles. The modification will disable the door chime but
keep the headlight and seatbelt alert.
A better way to do this is to dismount the box (very easy) and pop out the circuit board. The wires connect
to a card edge connector. Locate the pin that coresponds to the black/pink wire and put some thin tape
over the contact. This is actually the better way if you want to spend the time. It's easy to remove and
invisible.
