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.
This output is used for progressive door unlock. A progressive unlock system unlocks the driver's door when the
unlock (disarm) button is pressed and unlocks the passenger doors if the unlock (disarm) button is pressed again
within 15 seconds after unlocking the driver's door. The BLUE wire outputs a low current (-) pulse on the second
press of the unlock button of the transmitter. This negative unlock output is used to unlock the passenger doors.
NOTE:
The second unlock output feature is not available if the double pulse unlock feature
is turned on.
Connect this wire to the optional domelight supervision relay as shown below:
IMPORTANT!
This output is only intended to drive a relay. It cannot be connected directly to the
domelight circuit because the output cannot support the current draw of one or more light bulbs.
H1/9 BLACK /WHITE (-) 200 mA domelight supervision output
