LIGHT HOOKUP
A 7 pin electrical socket is provided to plug the
electrical control plug from your truck or tractor. See
figure 1.
This will operate signal, tail, clearance and brake
lights.
Depending on make and model of truck, it may be
necessary to install a light converter. (Meyer part
#56-0028). Converter allows signal lights and brake
lights to operate according to DOT lighting.
HYDRAULIC HOOKUP
Connect hydraulic pressure lines from the hydraulic
power supply (Wet kit) to the pressure and return lines
as illustrated on figure 1. The pressure relief on the
wet kit pump must be adjusted to have 3500 PSI to
the system under load. A gauge has been provided
(Serial #0891231 & later) to provide an easy reference
for pressure. Do not exceed 3500 PSI as motor failure
could result.
AIR BRAKE HOOKUP
Connect the control line (blue) from your truck air
supply to the blue gladhand on the trailer. Connect the
tank supply line (red) to the red gladhand on the
trailer. See figure 1.
