Hello,

I'm going attempt to install an alarm in my car. But I have some questions. For example, in the diagram it says that wire for the Door Trigger is RED / White(-). Does that negative sign mean it is a negative trigger? Also, the diagram lists a Door Lock, Door Unlock, Driver's Lock, Driver's Unlock and Passenger Unlock. What are all those for? I can unlock all the doors by turning the key twice in the driver or passenger door. Is that what those are used for? The car is a 1999 Nissan Maxima. Only security it has is the transponder chip in the key. The alarm I'm going to install is an old unit I removed from a previous car, Excalibur AL-900JX. Thanks!

e.n. :)

Will I need to use any relays?

You will not require to use relay, but you will need to set the alarm unit to a double pulse in order to unlock the doors.

i don't think the alarm has the option for double pulsing. I searched google and came up with DEI 452T. Hopefully I can get one locally. Thanks!
