NOTE: The blue and orn/brn breakaway switch wires and
the white and black wires are used only with trailers

Battery (Option)
A battery operates the hydraulic pump motor that lowers
and raises the trailer bed. If the trailer has electric brakes,
this same battery supplies the power to operate the trailer
brakes if the trailer uncouples from the tow vehicle activat-
ing the breakaway brake switch. The battery may be kept
charged either by the tow vehicle or by an available trickle
charger. Be sure to check, maintain and replace the bat-
tery according to the battery manufacturers instructions.
