This means that you need to find a wire that has a 200 - 250 mA negative output on the alarm. Most of the time it will be a trunk release output, AUX channel output or depending on the application it could be the starter disable output.

If you want to indefinitely disarm the factory alarm, you can GROUND the factory alarm DISARM wire. As long as it is grounded the factory alarm should be disabled. Once you remove ground from this wire, the factory alarm will become active again.

Good Luck!
