Purple Wire: (+) Door Trigger Input

If the vehicle's door courtesy light switches + 12 volts when the door is opened, (Some Fords and some

Imports), you must connect this wire to the positive output from one of the vehicle's door pin switches.

In most cases, the Purple wire will need to be connected to only one door switch no matter how many

doors the vehicle has as most door lighting circuits are wired in parallel. If this wire is active when the

system is armed, the siren will emit three chirps. When the zone clears, the siren will emit 1 chirp to

confirm full arming. See below for wiring details.

Dark Green Wire: (-) Instant Trigger Input

This is the instant on ground trigger input wire. This wire must be connected to the hood and trunk pin

switches previously installed.

Note: This wire will be shunted when remote control channel 3 is accessed, (trunk release). This wire

will remain shunted all the while there is ground present and for 5 seconds after the ground is removed.

This allows the operator to open the trunk via the remote transmitter without having to first disarm the

alarm system. See below for wiring detail.
