Factory alarm broken

Any of you ever had a Mopar EVS II alarm in it? I had one put in while I was in Shreveport, LA and haven't needed it since I moved to Vt... wouldn't be a big deal to leave it in... but the on/off/arm/disarm/blinky button has gone bad. the dealer can't get them, the alarm company is a ghost.... All I need is the switch! and can't find one.-
-guys on the trail call mine the "barking jeep"

Is it a little black box with a switch and a red light??

reply:

The broken fixture is not the box where you can adjust the alarm's sensitivity, but in the little red light/ switch that turns it on and off. It is 3 low voltage wires that just activate the switch and blink the dash light. ....
Of course, the smallest part broke, I would be happy with a blinking red light and a toggle switch... anything really that would turn it off and on.

Any ideas how to hotwire the thing?
