    2012 Pete 386.
    Have no power going back to reverse lights.
    I and have continuity from reverse light pin in rear bumper to backup switch on trans and at chassis node pin. No power.
    I found a rubbed wire for the orange wire going to backup switch on trans, thought that would fix it but no luck.
    Weird part is, when I plug in the connection at the back bumper partly the alarm will sound, but plug it in all the way and it kills it. Seemingly my alarm is getting power from the tail lights which doesn't make any sense seeing as it should come from reverse lights. HELP ??

    Remove the white light completely... No alarm is a good thing IMO.

    I think alarms are to warn that the person reversing is inexperienced at it. They always seem to take longer than most anyone else.
