Weight-Distributing Hitches and
Weight Carrying Hitches

A. Body-to-Ground Distance

B. Front of Vehicle

When using a weight-distributing
hitch, the hitch must be adjusted so
that the distance (A) remains the
same both before and after coupling
the trailer to the tow vehicle.

Safety Chains

Always attach chains between the
vehicle and the trailer. Cross the
safety chains under the tongue of
the trailer to help prevent the tongue
from contacting the road if it
becomes separated from the hitch.
Always leave just enough slack so
the rig can turn. Never allow safety
chains to drag on the ground.

Trailer Brakes

A loaded trailer that weighs more
than 450 kg (1,000 lbs) needs to
have its own brake system that is
adequate for the weight of the
trailer. Be sure to read and follow
the instructions for the trailer brakes
so they are installed, adjusted, and
maintained properly.

Because the vehicle has antilock
brakes, do not try to tap into the
vehicle's hydraulic brake system.
If you do, both brake systems will
not work well, or at all.

Trailer Wiring Harness

Basic Trailer Wiring

The trailer wiring harness, with a
seven-pin connector, is located at
the rear of the vehicle and is tied to
the vehicle's frame. The harness
connector can be plugged into a
seven-pin universal heavy-duty
trailer connector available through
your dealer.

The seven-wire harness contains
the following trailer circuits:

.

Yellow: Left Stop/Turn Signal

.

Dark Green: Right Stop/
Turn Signal

.

Brown: Taillamps

.

Black: Ground

.

Light Green: Back-up Lamps
