I recently bought a used '99 Suburban with the Automate AM1 (thats all the info on the model I was able to find) alarm. I have no idea how to program the thing, the parking lamps dont flash when the alarm goes off or it arms/disarms, I get no arm/disarm chirp, and it doesn't lock/unlock when I turn the ignition on or off anymore (it used to, I think) I can't find the installation/owners manual anywhere online. Help, please?
