Downloaded from www.Manualslib.com manuals search engine Visor Vanity Mirror (If Equipped)
Some visors have mirrors built in, with or without
lamps. Just lift the mirror cover
on each visor to turn the
lamps on, if you have them.
Lighted mirrors also have a density switch
to make the
mirror lamps brighter or dimmer.
Accessory Power Outlets (Option)
If you have accessory power outlets, you can plug in
auxiliary electrical equipment. Just pull up from the
bottom of the door and follow the proper installation
instructions that are included with any electrical
equipment that you install.
Passenger vans also have
two accessory power
outlets located
on the passenger’s side of the engine
cover console.
Another accessory power outlet
is located on the
driver’s side behind the third row seating position,
near the floor.
These circuits are protected
by a fuse and have
maximum current levels.
NOTICE:
When using the accessory power outlets, maximum
electrical load must not exceed
25 amps. Always
turn
off any electrical equipment when not in use.
Leaving electrical equipment on
for extended
periods
will drain your battery.

Downloaded from www.Manualslib.com manuals search engine Trailer Wiring Harness
If you have the optional trailering package, your vehicle
will have an eight-wire harness, including
the center
high-mounted stoplamp battery feed wire. The harness
is stored on the passenger side of
the vehicle near the
rear wheel well. This harness has a
30 amp battery feed
wire and no connector, and should be wired by
a
qualified electrical technician. After choosing an
aftermarket trailer mating connector pair, have the
technician attach one connector to the eight-wire trailer
harness and the other connector to the wiring harness
on
the trailer. Be sure the wiring harness on the trailer is
taped or strapped
to the trailer’s frame rail and leave it
loose enough so the wiring doesn’t bend or break, but
not
so loose that it drags on the ground. The eight-wire
harness must be routed out
of your vehicle between the
rear door and the floor, with enough
of the harness left
on both sides so that the trailer or the body won’t pull it.
If you do not have the optional trailering package, your
vehicle will still have a trailering harness. The harness is
located near the passenger’s side rear wheel well. It
consists of six wires that may be used by after-market
trailer hitch installers. The technician can use the
following color code chart when connecting the wiring
harness
to your trailer.
Brown: Rear lamps.
Yellow: Left stoplamp and turn signal.
0 Dark Green: Right stoplamp and turn signal.
White (Heavy Gage): Ground.
Light Green: Back-up lamps.
White (Light Gage): Center High-Mounted Stoplamp.
Blue: Auxiliary circuit (eight-wire harness only).
0 Orange: Fused auxiliary (eight-wire harness only).
Store the harness in its original place. Wrap the harness
together
and tie it neatly so it won’t be damaged.
