Since most newer vehicles come equipped with a factory alarm system, it is sometimes necessary for the factory alarm to be armed/disarmed when unlocking the doors and disarmed while remote starting the vehicle.

note: Some vehicles use a + trigger system. Use the www.designtech-intl.com website to determine if your vehicle has a + trigger system. If this vehicle has this sys- tem call 1-800-477-1382 for live technical assistance as special 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 Directed Technical Support at 1-800-477-1382.

Locate the factory alarm arm/disarm wires using the web site vehicle information. Once the suspect wires are 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 drivers door cylinder. Turn it to the unlock position and hold it when testing for the disarm wire. The LED tester should illuminate Green and will extinguish when the key is released.

When the correct wire has been found, solder the LIGHT Green/Black (H1/7) wire of the main harness to the wire which activates in the unlock position when the key is turned. After this wire has been connected wrap the connection with electrical tape.
