This is alot easier than you are making it out to be. If you have a bitwriter, scroll through the channels and check out the options, I believe the puple w/black wire (Think its channel 5) which is normally a validity output (For window control) can be switched to a latched output. I am absolutely certain that at least one channel on that alarm has the ability to be programmed as a latched output, I used to have a Viper 600 setup with a latched output to lock and unlock my shop door. You can definitley do this with your clifford, and some lights.
