    I need to install a back up alarm.. but i thought i could save $ by just running a wire from where the old reverse alarm was wired into... to my dump alarm. so instead of having two alarms i could just use that one alarm. but i cant seem to get it working seems simple but the reverse lights stay on when i connect the wires and when put in reverse no sound. the alarm does work. jus tnot for reverse lights.. i know it isnt that clear but anyone have any ideas or if its even possible for this to work

    Sounds like you need a diode on each positive wire going to the alarm or a relay for each wire going to it. The relay would be the better way but is more costly.
