1. Go to Radio Shack or any electronic parts store. Get a "Pulsing
Piezo Buzzer". It sounds intimidating, but all it does is go "beep
beep beep". Make sure it operates on 12VDC systems. (Most work over
a range - for instance, mine works from 3 - 28VDC. That will work
just fine.) Radio Shack has 5 or 6 to choose from, but I picked the
best one according to tone, volume, size, current, and quality. I
got part "#273-066a" and it works great in all respects. It runs about
$5 bucks, and already includes a pulsing driver circuit.
2. Now, when you get the buzzer, it will already have 2 stripped wires
coming off of the buzzer - a positive wire (red) and a ground wire
(black).
3. Solder a 3A in-line fuse onto the red (positive) wire, and splice
the end of the red wire (now with a fuse in between the buzzer and
the target power source) into the parking lights/turn signal fuse
hookup (I slaved it onto the fuse itself, but you can find the color-coded
wire that comes out of the back of the fuse box to make the install
a little cleaner if you wish.
4. Check your Del Sol Technical Service Manual, Chilton's etc. for
the correct color. Or you can just do it the easy way like me and
slave it to the fuse). Why not the headlights, you ask? Well, the
regular headlights are on a totally separate circuit than the brights.
So if you wire it into the parking lights, the buzzer will notify
you regardless of whether you leave your lights or brights on, because
the parking lights are on no matter what the headlights are doing.
5. Splice the black wire (ground) into your windshield wiper fuse
hookup (The same deal goes for this hookup. Take the easy route and
stick it in with the fuse, or go the clean route and splice it into
the correct wire coming out of the back of the fusebox. Your choice.)
6. Slap a little double-sided tape to the back of the buzzer, and
stick it onto something (I stuck it to the side of this wiring> harness
thing, just because it was clean, flat, and plastic. Try to avoid
metal, because there's too much temperature variation> and the tape
will keep falling off.) You can also screw the buzzer to something,
because it has 2 holes built in for screws. Use SHORT, SMALL screws
to avoid screwing into something live, or just tape because it's a
little easier than maneuvering a drill up under the dash. The buzzer
weighs practically nothing anyway.
7. Make sure the ignition is off, and turn on your lights. The buzzer
should start beeping at you to "turn off your lights stupid!" If it
doesn't, then: 1. You probably did it wrong. Follow the steps again,
a little SLOWER this time. 2. You blew the in-line 3A fuse when you
touched the power source (a little spark sound.) Replace the fuse
and it should work. 3. You hooked up the red and black wires backwards.
Switch them and it should work. One more note: If you have a car alarm
that flashes your parking lights, you will hear the buzzer beep as
your parking lights beep. This is totally normal, and makes sense,
because your alarm is flashing your parking lights with the ignition
turned off. Besides, it sounds really cool as you arm and disarm your
alarm!
