second unlock output for clifford 750

I have a 2002 impala with a clifford intelliguard 750 and intellistart 4 installed. I did the installation myself and read about the second unlock feature it has, but never bothered to hook it up. Now I'm interested in hooking up this feature, but i dont have the slightest idea of how to wire it. Does anyone have a diagram or can me tell how this feature should be wired up? Thanks!cedric

Second unlock is for door priority.  If anyone can correct me please do so.  You would use the first lock wire to unlock the driver door.  the second unlock would control the rest of the doors.  You would go into the door and grab the wire thats connect to the driver door actuator.  Use a relay and give it a pulse to unlock when pressing your remote.  The second time you press your all your doors will unlock.
