Thanks, Joe. The only funny thing with the Hella setup was how the high beams ("long" here) were turned OFF by pushing the stalk when the Hellas were disabled by the switch. It's a bit odd and makes me a little suspicious concerning removal of the kit.
As for the alarm, the question was more in the direction of "are all aftermarket alarms basically installed the same way and how?"
The automatic arming can be disabled once I establish the model of the alarm and have it reset so I can provide a new PIN.
Thanks!
