RE: automatic door unlock

Shiraz - Wiring in an alarm to unlock the doors is easy. The following is
from my installation instructions for remote opening doors:

"If you are installing an alarm or keyless entry system, it is very easy to
connect it to the door lock circuit. Just connect the alarm unit's door
lock negative output wire to the brown/silver wire at the DMC relay/pulse
unit (the black box with all the wires sticking out of it just behind the
fuse box) with a parallel connector. Do the same with the unlock wire,
connecting it to the brown/pink wire. Be sure to read the alarm unit's
installation manual very carefully. With some the alarm output is
alternately positive then negative on the next pulse. This would cause
serious meltdown when tied into the DMC's "always negative" door lock
trigger circuit. You can remedy this by installing a 1N4001 diode (Radio
Shack) in each alarm trigger wire which will then allow only the negative
signal to pass. Solder the diode to the wire with its stripe toward the
alarm/keyless entry unit.

Some other tips on alarm installation for the do-it-yourselfer. To trigger
the alarm when either door opens attach the negative "door open" sensor wire
to the red/blue or purple/white wire that protrudes from the loom on top of
the center console hump, below the radio, on the driver's side. Both come
out of the same wiring plug at the end of one of the diodes located there.
Also, to make the parking and side lights flash, connect the proper alarm
wire to one of the red/green wires below the fuse box. And if you need to
connect to a wire that is "hot" only when the key is on, look for a
green/white wire coming out of the large loom just inboard of the fusebox."

Hope this helps. Give me a call if you need more info.
