H1/8 BLACK (-) chassis ground connection
Remove any paint and connect this wire to bare metal, preferably with a factory bolt rather than your own screw.
(Screws tend to either strip or loosen with time.) We recommend grounding all your components, including the
siren, to the same point in the vehicle.
H1/10 BROWN (-) horn honk output
This wire supplies a (-) 200 mA output that can be used to honk the vehicle horn. It outputs a single pulse when
locking the doors with the remote, and two pulses when unlocking with the remote. This wire will also output
pulses for 30 seconds when the Panic Mode is activated. If the vehicle has a (+) horn circuit, an optional relay
can be used to interface with the system, as shown below.
H1/11 RED (+)12V constant power input
Before connecting this wire, remove the supplied fuse. Connect to the battery positive terminal or the constant
12V supply to the ignition switch.
NOTE: Always use a fuse within 12 inches of the point you obtain (+)12V. Do not use the 10A fuse
in the harness for this purpose. This fuse is intended to protect the module.
