Wiring Connections - 8 Wire Connector
Negative Door Trigger Wire
The Green wire's function is an open door input to the control module for vehicles having negative switching door pin switches. An open or closing door
will affect the following operations:
A) When the security system is armed, opening a door will trigger the
the doors to relock.
B) If the Last Door Arming feature is utilized, after turning "off" the ignition switch and closing the door, the Last Door Arming sequence will begin. Upon
closing the last door, this is indicated by a siren chirp or horn honk, one parking light flash and a fast flashing LED Status Light. Thirty seconds after
the last door closes, the siren will chirp again (or the horn will honk again) and the parking lights will flash once again, indicating that the system is armed.
C) Opening a door while the exterior lights are on after disarming the
of the door. If the Last Door Arming feature is utilized, closing the door will initiate Last Door Arming.
D) If the Doors Lock With Ignition "On", and Unlock With Ignition "Off" features are turned on along with the Open Door Bypass feature, if a door is open
when the ignition switch is turned "on" with a door opened, the doors will not automatically lock; if a door is open when the ignition switch is turned
"off", the doors will not automatically unlock.
E) Opening a door during the 90 second Automatic Rearming cycle, or the 30 second Last Door Arming cycle will suspend that automatic function for as
long as the door is open. When the door is closed, the Last Door Arming sequence will restart.
F) If this wire is grounded at the time the security system becomes armed from the transmitter, the circuit bypass feature will leave the Green wire circuit
unprotected until the circuit becomes ungrounded.
G) If the system is triggered by the Green wire, the LED Status Light will flash 3 times and pause until the ignition switch is turned "on". The Information
and Programming Module's digital display will additionally show "d". The system does not have to reset itself for this feature to operate.
H) When the ignition switch is "off", if the Green wire becomes grounded, the LED Status Light will flash 3 times and pause for as long as the door is open.
This is the Zone Testing feature, which allows the installer or vehicle owner to visually see trigger circuits which are in a violated state.
I) If a door is opened and remote starting is attempted, the vehicle will not start and the EG-1800
If a door is opened after the vehicle has been remotely started, the system will go into an alarm state and the engine will stop running.
CONNECTION: Connect the Green wire to a wire in the vehicle which is common to all the door pin switches. The correct wire in this type of dome light/
door jamb pin switch system will have no voltage present and will also show chassis ground when the doors are opened, and up to 12 volts when the doors are
closed. The 12 volts present on the wire with the doors shut is simply voltage that the meter detects through the dome light bulb filament(s). When the door
is opened, a path to ground is presented to this voltage (known as ground potential), which causes the voltage to flow to ground (this is referred to as electrical
current). The completion of this circuit, caused by opening the door, resulting in current flow, causes the dome light bulb's filament to glow because of the
filament's resistance to the electrical current. The correct wire will show this change when any of the doors are opened. If the vehicle has delay dome lights,
remember to take this into account when testing the wire. If the car has a delay dome light the Circuit Bypass feature will allow the system to be armed from
the transmitter instantly and will start protecting the Green wire circuit when the dome light turns off. In Last Door Arming mode, the system arms 30 seconds
after the delay dome light turns off. The diagram on the following page illustrates a basic negative courtesy light system.
