    The towing company I just started with has 3 new Whelen Justice Light bars and a couple whelen edge's. Are they only programmable with a flasher module/switch or can you use the magnetic keychain that smaller whelen's have. I've got the keychain from my other job. If they do utilize the keychain, where is the sensor?

    Whelen products do not utilize magnet pattern change switches. You would need to use the pattern change switch or lead respectively. Glad someone is buying Mini-Justices, I have 4 in stock that won't move. :confused:

    the justice bars have to be programmed with the scan lock wire and a momentary switch. or you can just touch it to the power wire. there is no magnetic sensor on the bars

    all the recent whelen products have a white/w-purple stripe. touch to power only for a sec or so. if it dont have that wire you will need thats if it is a low power bar. low power bars are controlled via about 16 or so light gauge wires. those need to go to a switch. if the bar has only a main power cable with a smaller gray/blue wires it needs a b-link program to change the patterns. and a mpco1 or a mpco2
