This type of dome circuit is used in many Ford vehicles. Connect the violet wire to a wire that shows (+)12V when
any door is opened, and ground when the door is closed. This wire will report Zone 3.
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.
Connect this wire to an ignition source. This input must show (+)12V with the key in run position and during
cranking. This wire will report Zone 5.
CAUTION!
Make sure that the H1/9 wire cannot be shorted to the chassis at any point.
H1/9 YELLOW (+) ignition input, zone 5
H1/8 BLACK (-) chassis ground input
H1/7 VIOLET (+) door trigger input, zone 3
