Attaching Safety Chain
■ Visually inspect the safety chains and hooks for wear or
damage.  Replace worn or damaged safety chains and
hooks before towing.
■ Attach the safety chains so that they:
A. Cross underneath the coupler. See Figure 29.
B. Loop around a frame member of the tow vehicle or
holes provided in the hitch system (but,  DO NOT attach
them to an interchangeable part of the hitch assembly).
C. Have enough slack to permit tight turns, but not be
close to the road surface, so if the trailer uncouples,
the safety chains can hold the tongue up above the
road.
TRAILER SAFETY GUIDELINES
Figure 29.  Safety Chain Arrangement
for a Bumper Pull Trailer (Ball Hitch)
 
   WARNING — Safety Chains Rigging
Improper rigging of the safety chains can result in loss
of control of the trailer and tow vehicle, leading to death
or serious injury, if the trailer uncouples from the tow
vehicle.
 Fasten chains to frame of tow vehicle.  DO NOT
fasten chains to any part of the hitch unless the hitch
has holes or loops specifically for that purpose.
 Cross chains underneath hitch and coupler with
enough slack to permit turning and to hold tongue
up, if the trailer comes loose.
Connecting Trailer Lights
Connect the trailer lights to the tow vehicle’s electrical
system using the electric connectors at the front of the trailer
(tongue). Reference the wiring diagram shown in the trailer
wiring diagram section of this manual. Before towing the
trailer check for the following:
■ Running lights (turn on tow vehicle headlights).
■ Brake Lights (step on tow vehicle brake pedal).
■ Backup Lights (place  tow vehicle gear shift  in reverse).
■ Turn Signals (activate tow vehicle directional signal lever).
Uncoupling the Ball Hitch
Follow these steps to uncouple ball hitch from tow vehicle:
■ Block trailer tires to prevent the trailer from rolling,before
jacking the trailer up.
■ Disconnect the electrical connector.
■ Disconnect the breakaway brake switch cable. Promptly
replace the pullpin in the switchbox.
■ Before extending jackstand, make certain the ground
surface below the jackstand foot will support the tongue
load.
■ Rotate the jackstand handle (or crank) clockwise.  This
will slowly extend the jack and transfer the weightof the
trailer tongue to the jack.
 
   WARNING — Electrical Connections
Improper electrical connection between the tow vehicle
and the trailer will result in inoperable lights and electric
brakes, and can lead to collision.
Before each tow:
 Check that the taillights, brake lights and turn signals
work
 Check that the electric brakes work by operating the
brake controller inside the tow vehicle.
