Factory Alarm Disarm
Since many newer vehicles come equipped with a factory alarm it
is necessary to disarm it when unlocking the doors or during
remote start. Do not mistake a factory alarm with an immobilizer
system. They each require different disarm operations.
Locate the factory alarm disarm wire using the web site informa-
tion. Once the suspect wire is located, place the multi-meter's red
lead to a (+)12 volt constant source and secure it. Put the multi-
meter in the DC position then probe the suspect wire with the
black lead of your meter. While probing the wire, place the key in
the driver's door cylinder. Turn it to the unlock position and hold
it when testing for the disarm wire. The multimeter should read
12V and will go back to 0V when the key is released.
When the correct wire has been found, solder the BROWN/WHITE
wire of the 6-pin harness to the wire that you determined to be
the factory alarm disarm wire. After this wire has been connected
wrap the connection with electrical tape.
note! Some vehicles use a + trigger factory alarm
system. Use the website to determine if your vehicle
has a + trigger. If your vehicle has such a system call
1-800-477-1382 for live technical assistance as spe-
cial wiring and an additional relay is required.
note! On some vehicles the Factory Alarm Disarm
wire is connected to a Body Control Module or a Door
Module. If you find this configuration, please call
Technical Support at 1-800-477-1382.
