96 chrysler concord oem alarm

I have a customer with a 96 chrysler concord, When ever he starts the car The OEM alarm go's off and the lights start flashing (turn signals and headlights) and about a secont or two the car dies. Theres no flashing lightsIs in the dash or check engine being on. Is there any way to disable the factory alarm? Also the door locks dont work inside im guessing a fuse, but i haven had a chance to look in to the car fully. any ideas to get a heads up, going to check on car today for any bad fuses and details. Thanks

there is a lt GREEN/ orange wire in the drivers kick. this wire requires a negative pulse before start. use the Disarm wire of the RS or an output that pulses before start and it will disarm the factory alarm
