Got the CLP/SSM today and plugged it in, even with the old corroded Tow Alarm everything seems to work now. Car is in garage and not leaving until I weatherproof. But it does chirp so that is good news. Still waiting for the weather-strip, during summer they don't stock much so bought the kind recommended from Lowes on-line. I have the hatch open and when I locked the car I got two beeps, guess it is telling me I have a open door/hatch. Still waiting fro the replacement Tow Alarm.
