    The abs power feed from your truck is the center blue wire in your pigtail. This should be powered up with the key on.

    The power feed to your yellow ABS light on the side of your trailer, comes from the ABS controller
    . Follow your sensor wires from your brakes to the air valve. This is your wabco controller.
    This is where your line for your abs light should be.
    Good luck

    I have looked all over the wabco controller and the wiring harness going to it. I thought maybe a pigtail would come out of the harness somewhere but didn't find anything. I appreciate your help.

    Who ever removed the wire to the light, probably removed the entire wire including the plug to the module.

    wabco trailer abs module wiring diagram

    Call a Lufkin dealer. They should be able to email you a schematic for your trailer.
    Good luck
