Hi, I just fitted an alarm(with built in relays for central) to my Z and am about to install the door actuator. I have the following wires from the alarm: UNLOCK - NO UNLOCK - COM UNLOCK - NC GROUND WHEN ARMED LOCK - NO LOCK - COM LOCK -NC 2 STAGE UNLOCK I have both 5 wire and 2 wire actuators, anyone know what wires connect to what? My best guess, after reading http://www.the12volt.com/ is: BOTH "NO" - 12V EACH "COM" - to one wire of the 2 wire actuator BOTH "NC" - GROUND But then there is the seperate ground wire, which is confusing.
