Thanks. Im trying to figure out how to use that to activate another relay to drive a separate horn and piezo sirens while using the parking flash as a trigger.

I have seen some of the 'off brand' systems that do not provide a negative until the alarm is actually tripped (going off) even though they are listed as a ground when armed output.

according to the user manual on this alarm it says that you can use the orange ground when armed for the optional starter kill relay. so I guess it is a true ground when armed.

No it doesn't, it very well may only go to ground when the alarm is being triggered. I have seen plenty of systems that claim it is a 'ground when armed' when it was in reality a 'ground when going off'. Just test the output with a DMM, arm the system and see if the wire provides a ground.
