    2014 t680 my truck marker lights all won't come on they still flash with turn and hazard but otherwise stay dark meanwhile the clearance lights above the windshield all work.
    all the lights on a trailer work fine
    I'm either not finding the correct fuse or its something else.
    any tips?

    Sounds like you've got a likely wiring harness issue. If that truck's still under warranty, I'd leave that to KW, because wiring on these trucks is a MF.

    Try updating the CECU software. .5 hours at a dealer. Everything runs through this critter.
