H1/7 VIOLET (+) door trigger input: This wire is used in vehicles that

have a positive (+) switched dome light circuit . Connect the violet wire

to a wire that shows (+)12V when any door is opened and ground,

when the door is closed

H1/8 BLACK (-) chassis ground connection: We recommend that

you do not use a factory ground. Ground all your components

including the siren, to the same point in the vehicle, (preferably the

kick panel). Scrape away any paint and use a factory bolt or make

your own ground with a self-tapping screw and a star washer.
