Ok now so you want the radio to turn on when the alarm goes off and turn it off when the alarm goes on. Is that what I am understanding???

Does your alarm have a ground when armed output???? If it does here is what I would do. I would go out and buy a relay and hook it up the following way:

Connection 86 - Hook up to constant 12v fused at 20A >>>>>>>>>>>>>>Hook both of these

Connection 85 - Hook up to ground when armed output on alarm wire to a high current

Connection 30 - Hook up to constant 12v fused at 20A >>>>>>>>>>>>>>>12v wire and fuse it!!!!!

Connection 87 - Not used

Connection 87a - Hook up to the remote turn-on wire behind the radio

This was when the alarm is armed the relay will turn the raido off and when disarmed it will turn it on. Hope this helps. Also remember, if you ever leave your car unarmed the radio will stay on. You might think about putting a toggle switch somehwere so that you still have control of it. You can interrupt Connection 85 or 86 and putting a toggle switch in series so that way you can prevent the relay from turning on when you don't want it to.

Yup, I looked at the manual for this alarm and yes the connections stated abve are correct. Use your orange wire on your larm and hook it up to the Connection 85 on your relay. By the way this wire is a constant ground when armed and neutral when disarmed and there are no pulses on that wire. Hope this helps.
