Im still trying to figure out how to get the Alarm system to operate properly. After 14 seconds with the key on and the engine not running alarm should sound. Or if OIL/fuel/volts are low you should also get a Alarm. I found a new Alarm from ebay and it still does nothing.

Does anyones Alarm work?
Could it be the connection/ground from the sending units?


I have the Purple and Blue/White wires hooked up.
