TOWING & HANDLING

RIVING
LCOHOL
Driving after drinking or taking drugs
(including some prescriptions and/or over-
the-counter medications) can lead to an
accident. Studies have shown perceptions
are less sharp, reflexes are slower,
drowsiness may be experienced and/or
judgment may be impaired.
The presence of alcohol in significant levels in
the blood increases the probability that the
driver will be involved in an accident. Exercise
your good judgment and encourage others to
do the same. Know the legal alcohol limits
and do not exceed them. Be aware of your
personal limits, which may be lower than the
legal limits. Should you ever exceed your
limits or find your driving is impaired, find
alternative transportation. NEVER DRINK
AND THEN DRIVE.

NEVER use the breakaway switch and
trailer brake system as a parking brake.
Doing so would create a high amp draw on
the battery and converter. This can cause
damage to wiring, connectors and the
breakaway switch.
The breakaway switch is a crucial part of the
RV braking system. Located near the fifth
wheel pin box, this switch will apply the trailer
brakes if the RV becomes detached from the
tow vehicle. Attach the breakaway switch
lanyard (cable) to a permanent part of the tow
vehicle when hitching the RV. If the RV
becomes detached from the tow vehicle, the
pull pin will be pulled from the switch. This
automatically causes the switch to "close" and
activates the RV brakes.

An auxiliary battery must be purchased and
correctly installed to activate the breakaway
switch.

There are two types of 7-way connectors: one
has flat pins (which are often referred to as
blades); the other has round pins. The round
pin style is very rare. The RV style Pollak 7-
way trailer plug with flat pins (or blades) is
more common.

A 7-way wire harness/connector plug (also
called the trailer plug) is wired into your RV to
connect electrical power from the tow vehicle
to the RV for travel. Generally speaking, it is
located under the fifth wheel gooseneck, on
the off-door side, near the pin box. Keep the
trailer plug storage compartment door closed
