mailer. Wiring Harness
K2373
The 7-wire harness is stored under your vehicle along the rear\
frame
crossmember. The harness has a
30 amp in-line fused battery feed wire and
no connector, and should be wired by a qualified electrical se\
rvice person.
Securely attach the harness to the trailer, then tape or strap\
it
to your
vehicle’s frame rail. Be sure you leave it
loose enough so the wiring won’t
bind or break when turning with the trailer, but not
so loose that it drags on
the ground.
Store the harness in its original position. Wrap the harness t\
ogether and tie it neatly
so it won’t be damaged.

Flow-Through Ventilation System
1
K2 1 90
Your vehicle’s flow-through ventilation system supplies outside air \
to the inside
of your vehicle when
it is moving. With the side windows closed, air will flow
into the front air inlet grilles, through the vehicle and out the rear air exhaust
valves. Outside air will also enter the vehicle when the heate\
r or the air conditioning fan is running.
Ventilation Tips
e
e
e
Keep the hood and front air inlet free of ice, snow, or any other
obstruction (such as leaves). The heater and defroster will work far
better, reducing the chance of fogging the inside of your windows.
When you enter a vehicle in cold weather, turn the blower fan\
to
HI for
a few moments before driving
off. This helps clear the intake ducts of
snow and moisture, and reduces the chance of fogging the inside of
your windows.
Keep the air path under the front seats clear of objects. This helps air
to circulate throughout your vehicle.

Air Vents
K2315
You will find sir vents in the center and on the sides of your instrument
panel. You can move the vents to direct the flow
of air, or close the vents
altogether. When you close a vent, it will increase the flow of air
coming out
of any vents that are open.
If your vehicle does not have air conditioning, there are air vents below the
instrument panel. Each vent has a handle with a vent symbol on it. Use the
handle to open and close the vent.

Heater Output
Optional Engine Block Heater
If your engine is equipped with an optional engine block heater, you can use
it during initial start-up in cold weather (20"F,
-8OC, or lower) to help heat the
passenger compartment faster. Because an engine block heater war\
ms the
engine coolant, your vehicle's heating system can provide some \
heat as soon
as you start the engine.
The use of an engine block heater also reduces the time it takes for the
engine to reach normal operating temperature, and shortens the time it takes
the heater to reach full output. For more information, See "Engine Block
Heater" in the Index.
