When you lock or unlock the doors with the long key it turns a switch on the
back of the lock cylinder to engage or disengage the alarm - the alarm is
triggered by a change in the voltage - opening a door turns on the interior
lights which sets off the alarm . The rear hatch is similarly equipped the
contact pin switch ,on the bottom of the receiver, which provides a ground
to the interior lights and the voltage change triggers the alarm

Don,

I just did this yesterday on my car.  I lost my long key and only have the
short one so I could either wait for a new key (months), or disable the
alarm.  All you have to do is take the lower parcel shelf off the
passenger side, then remove the 5 black screws (inside glovebox) and 3
bolts (underneath glovebox) that hold the glovebox in.  Slide the box out
and the alarm brain should be tucked behind the left metal support beam
(it actually is one big relay).  Disconnect the two plugs from it and you
should see a diagram of the pin numbers.  What you want to do is to take
some suitable terminals (from Autozone, etc.) and a short length of wire
and crimp one on each end.  Then plug one end into the #30 socket on the
small white connector, and the other end into #87a on the big black
connector.  Be careful to connect the correct sockets together or bad
things will happen.  Remember when you look at the diagram that you're
looking at the relay end, and the plug is a mirror-image.

FYI information: pin #30 is the battery voltage input into the relay, and
pin #87a is is the battery voltage (with ignition switched on) output
presumably to the ignition relay.  So, when the alarm is set off, it will
not let power go through it out of #87a.  Instead it will divert battery
voltage to pin Hn which will set off the horns and lights.

Also, someone noted that their battery was drained after doing this. 
There is also pin #15 input into the relay which is battery voltage with
ignition switched on.  If jumpering pins #30 and #87a drains your battery
over time, try instead to jumper #15 and #87a.  I forgot to try this
yesterday but theoretically it should work just as well, and only drain
battery voltage with the ignition on.

My car is an '86, so there may be slight variations with your 90GT. 
Sorry, that wasn't in one sentence, but I hope it's "simple" enough.
