    First time installating car alarm, need help

    here is the manual on the scytek astra 777 alarm





    and this is the wiring diagram for my 2000 ford explorer

    i already mounted the brain, the siren and the shock sensor.
    also wired them.

    i haven't wired the horn, parking lights and the doors. i need help on this.
    the wiring is kinda confusing.

    for the horn, it says that the wire is negative and must use a relay, how will i wire a relay with a negative wire?
    for the parking lights, do i just choose which wire polarity i will hook up from my car and just set the jumper? how will i know if the parking lights exceeds 10 amps and needs a fuse?
    i'm totally confused on how to wire the doors. don't need the triggers just need the unlock and lock feature.


    i **** at this..
    thanks in advance to anyone that can help!

    the alarm has a neg output for the horn=no need for a relay to horn, just direct connection

    parking lights will be fine with a direct connection with the Scytek

    why no door triggers? the shock sensor won't be much of a theft deterrent just on its own. hook up door triggers to domelight, i would also add a glass breakage sensor at the minimum.

    as far as doorlocks, well you sir have a pain in the *** vehicle for door locks. this truck has what is the GEM module. the doorlocks in essence "go to sleep" and can cause false triggers all night long.

    you will need to pick up some diodes and a use the bottom diagram.


    the BCM is located to the left of the radio behind the dash.
