LIGHT GREEN BLACK (-) 200mA 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 following instructions available on www.readyremote.com. 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 LIGHT GREEN/BLACK wire of the 9-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.
Some vehicles use a (+) trigger factory alarm system. Use the website resource 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 special wiring and an additional relay is required.
