I am sure this has been discussed but after a search or to I can't seem to find what I am looking for so. I am installing an alarm on this car, it has not starter wire as everbody knows, I am wondering how everyone else hooks these up when installing an alarm? i was thinking instead of a starter kill since it has one kind of how about splitting the ignition circuit. Be gentle alarms are not my thing.

The starter wire is under the hood at the PCM, yellow wire, here is DEI's description:
CHEVROLET, COBALT, 2005, Starter
The PCM (Powertrain Control Module) is on the driver side fender, in front of the underhood fuse block.

I have found all 4 door triggers, my problem is the pulse when they are opened to ground seems not be strong enough to trigger alarm. I have ground RED / white trigger input wire and it will trigger. I need a diagram of how to wire up a relay to strengthen the ground pulse I think, not 100% sure though . Any ideas I am installing a compustar 1wsh-s, alarm only. -------------

2 wires at the bcm. diode isolate them with the bands on the diode at the bcm side.
