auxiliary harness wiring guide
H2/1 BROWN (-) horn honk output: This wire supplies a 200 mA (-) output that can
be used to honk the vehicle’s horn. It provides a pulsed output when the security sys-
tem is armed/disarmed and in the triggered sequence or in panic mode. In most vehi-
cle’s with (-) horn circuits this wire can control the vehicle’s horn without adding a
relay. If the vehicle has a (+) horn circuit, an optional relay must be used to interface
with the vehicle’s horn circuit.
IIMMPPOORRTTAANNTT!!
Never use this wire to drive anything but a relay or a low-current input!
This transistorized output can only supply (-) 200 mA, and connecting directly to a sole-
noid, motor, or other high-current device will cause the module to fail.
H2/2 GREEN for arm input: Connect either this GREEN or H2/4 BLUE wire to a wire
that changes state when the doors are locked using the factory keyless entry transmit-
ter. This wire can accept a positive (+) or negative (-) input. The vehicle’s power door
lock motor wire is ideal.
NNOOTTEE::
These wires (H2/2 and H2/4) can be used for arm and disarm interchangeably.
H2/3 RED disarm defeat input: This wire is used to prevent the interior door lock
switches from disarming the system. To determine the best location to interface this
wire, first test the operation of the remote keyless entry system. When unlocking the
doors with the factory remote transmitter, does the driver’s door unlock first? Most
vehicles operate this way. If this is the case connect the RED wire to the passenger
unlock motor wire. When testing this wire be sure that it shows 12V (+) when the
unlock button on the factory transmitter is pressed twice. If the factory keyless entry
system unlocks all of the doors at the same time, connect this wire to the unlock wire
coming from the lock switch.
H2/4 BLUE disarm input: (See H2/2 GREEN description). Connect the opposite wire
to a wire that changes state when the doors are unlocked using the factory keyless entry
transmitter. If the factory transmitter unlocks the driver’s door first, the BLUE wire must
be connected to the wire that changes state when the driver’s door is unlocked by itself.
