  • DFS Alarm Installation

    so my new head unit has a built in car alarm, just in time too cause there has been a handfull of break ins on my street recently.

    The alarm is hooked up to the door switch, and when the door is opened there is a set time until the alarm goes off..

    But i need to find out which wire to splice. and where
    The install manual says the domelight signal.. So where do i find that?

    i spent some time with my head under the dash tonight but couldn't make sense of any of the jumble of wires..

    you could trace the cable coming from the switches which are pushed in when the door is closed. measure wheter it switches the ground or the +12. Dunno what your headunit requires, I think it would be the 12Volts...
    If at first you don't succeed.........
    destroy all evidence you tried

        i have that same feature with my deck and i tried to hook it up but realized that it is more trouble than its worth. i ended up going out and getting an alarm instead. that way it doesnt wait x seconds to go off, it goes off right away. if the person wanted to, they could just rip out the deck and take it before it goes off, or just snip the battery within the specified time. i feel that those DFS alarms are a nice feature, yet, they are a false sense of security.

          i kinda like false sense of security considering the cost...

          also, you could set the alarm up with a short delay so it would go off soon after the door opens, and use a keyremote to disarm it.
