First off.... sorry for digging up this nearly 2 year old thread.... but it'* still unresolved.
I've checked the wiring, and it seems proper.
The issue with both the cars is that the factory alarm arms if any door is open when the the car locks. So if I'm walking away from the car, thinking that all doors are closed, and a passanger still has their door open when I press lock.... damn... the next time I open the door the factory alarm will go off.
The factory manual says to turn off the alarm, to open the front doors with a key, or use the factory remote.
I've tried on both cars, both doors... using the key to unlock the doors does NOT shut off the alarm. I keep the factory remote in the 91 just incase I accidently lock the doors and one is still open.
The issue with the 97 is that it never came with keyless entry, thus no factory fob... doh. That means the only way to turn the alarm off, once it'* going is to disconnect the battery.
That'* why I really want to remove/disable the factory alarms in both the cars.
Does anyone know how?
