    I have hooked my tractor to other trailers and have the ABS trailer light on dash light up.
    But when I hook to my Direct trailer it will not light up on dash.
    Now the ABS light on the trailer will light and then go off when I apply the brake. If I unplug a sensor from Wabco ABS unit the trailer light will do a blink code. Why does this make me loose sleep ??

    Abs light coming on when braking. I think... Means your power to the abs ecu is not active, blue wire,, and it is drawing power from the brake light circuit.
    Good luck
