primary harness wire connection guide

H1/1 GREEN (-) closed loop
This wire can be used to protect a part of the vehicle where a trigger is desired when the wires of the connec-
tion are not in contact, rather than in contact. This closed loop connection is useful for protecting things such
as saddlebags, luggage carriers, etc. that could be easily removed from a motorcycle or other recreational vehicle.
Connect this wire through the object being protected and then to the battery ground loop. Then, if the contact
is broken on this wire when the alarm system is armed, the alarm will sound.
NOTE: When armed, the system checks to ensure that ground is present on this wire. If ground is
not present on this wire, the system will ignore the zone (see Table of Zones section of this guide)
and will not respond to the zone again until the system has been disarmed and rearmed.
H1/2 BLACK (-) battery ground
Connect this wire to the vehicle's negative battery terminal using a ring connector. We recommend grounding all
your components to the same point.
H1/3 LIGHT GREEN/BLACK (-) optional multiplexed sensor input
Inputs shorter than 0.8 seconds will trigger the Warn Away response, while inputs longer than 0.8 seconds will
trigger the full alarm sequence and report Zone 4. If installing an optional DEI
the blue and the green wires of the optional sensor to this input.
H1/4 ORANGE (-) ground-when-armed 500 mA output
This wire supplies (-) ground as long as the system is armed. This output ceases as soon as the system is dis-
armed. This wire can be used to turn on an optional sensor or to ready an optional accessory, such as a pager
module.
