Fifth Wheel wire loose

Where does this white wire attach to? Is this a ground wire? Located near the kingpin of the trailer.
  • It "could" be a ground. White wires are "usually" ground on RVs.
    Not much info provided. Wiring can be different RV to RV. Even same models.

    Any signs of a connection point in the area as the wire end appears frayed? Does the wire loop down and back up to the right side of the box? (looks like it in the pic) Have you followed the wire to where it may lead?
  • White usually indicates hot. Green is normally ground. But to be sure get out your VOM.
