Chris,
Thanks for the response. I have started checking the alarm system. Here is my finding.

Probing the Alarm control module connection:

Required test: Expected results: Actual result:

* 30 & 78a Test lamp light (Test lamp did not light)
* Hn & 30 Test Lamp light (Test Lamp did not light)
E/A & 31 Alarm on 2- 3 oms (2.4 ohms)
E/A & 31 Alarm off 4 - 5.5 Oms (4.5 ohms)
MK & 30 Test Lamp on Test lamp on/ Press trunk switch off
61 & 30 Test light on Test light on (Ignition on light off)
* 15 & 31 Test light go out with Ignition on (Opposite) Light go on w/ignition
* T & 30 Open door Test lamp light Test lights did not light
31 & 30 Test lamp light Test light light on

* Indicates faults found. Still working on these- problems seem to be pointing at Ignition wiring with the opposite reading on 15 & 31. I would attempt an alarm bypass, but i hesitated giving the reverse reading on 15-31..

Thanks again.

John
