    Splitter box must be your problem. The front foglights need to get cut out by the splitter box for the rear fog lights to work. Check the reverser switch on the tranny too.

    If you bought the rig used make sure sure someone didn't replace the fog light with a sun light.

    And BTW you can crank up the power on that FL 618 by increasing the compression gap to -.005".

    Good luck!
