Car Alarms: 93 Bonniville Alarms?, pontiac bonniville, gm system

Question
Recently my 93 Pontiac Bonniville would not start, I had it towed to a shop, they tested the starter and everything they said they could think of.  They said that my car has a stock alarm, and an after market alarm on it. Is there a way to disable one of the alarms, rather then taking it to the another shop to have someone reprogram the keychip, and both alarms?

Answer
Ok, there are 2 GM system here.

The FACTORY ALARM DISARM WIRE IS
light green |-| in the drivers door harness.

Once Located, splice into this wire with
a simular guage wire, and put it to
a solid chassis ground. This terminates
the OEM alarm functions entirely.

The PASSLOCK II however would need a bypass
module to disable it. (see IB-PLJX at www.PASSLOCK2.com)
That would circumvent that chip, and bypass it
for good.

Try the first and FEE method to see if
it does what's needed. If not, this PLJX
mod. is in stock :>)
