unknown alarm

I do not think that you are going to have much luck finding an install diagram for a piece of that age. If the device was built by Clifford, it was built when they were an infant company, and have since been bought out by DEI. If you have access to a small 12VDC power supply I would hook it up on a bench, make sure the power supply you use has short protection (most do) and test away to figure out which wire does what. It appears that the system has a door trigger, power, ground, ignition, and speaker output (siren) from the picture shown.Installer, IT support, and FFL. I need less hobbies.

Twelvvoltz, thanks for your response, that's exactly what I did and exactly what I found though I would still like to have the book just for future reference.
