Well, the alarm module is behind the glove box bezel, so you have to remove the top dash pad (4 screws at defrost, 3 above gauges, and 2 above the radio then gently pry at each end) and the trim around the radio to get the glove box trim out. Not too terribly bad. Please note that this is located left of the relays that are in the glove box access panel, so the entire bezel must come off.
According to the diagrams (included) in my '94 JGC Ltd manual, removing or clipping the cable (PK/OR) to pin 5 on the alarm module should prevent the system from being armed. I would leave the disarm cable (pin 4) on there just in case it gets tripped (somehow) and you have a way to turn it off. You might need to short pin 4 (VT/YL) (with power to the system) to ground to disarm the alarm if it's still active.
The main problem I see here, is that any time your battery is disconnected the Alarm will enter power-up mode, which will kill then engine and flash the lights (no horn) so you'll have to some how disarm the system. You might just run a momentary switch from Ground to Pin 4 to accomplish this, just put it in your glove box since it's all right there. You may even get away with shorting pin 4 to ground forever, I'm just not sure if this will resolve power-up mode.
If anyone can see an easier way here, please feel free to jump in. I don't think removing the module totally is an option as the PCM and the VTSS have dialog over the CCD. I don't know how extensive it is, might be read only from the VTSS for the 20 start rule and logging of failure codes from the VTSS, may be active in that it places restrictions on the engine when the system is armed though judging from the other connections it's not likely. In any case I've read that PCMs from vehicles with alarms can not be used on vehicles with out alarms.
