Accessory Power Outlets
(If Equipped)
If you have accessory power outlets, you can plug in
auxiliary electrical equipment. The accessory power
outlets are located near the center of the vehicle on the
lower part of the instrument panel. Just remove the plug
from the outlet and follow the proper installation
instructions that are included with any electrical
equipment you install.
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 20
amps. Always turn off any electrical equipment
when not in use. Leaving electrical equipment on
for extended periods will drain your battery.
Sunroof (If Equipped)
Your vehicle may be equipped with a power sliding
sunroof. To open or close your sunroof, the ignition or
RAP needs to be on. See ªRetained Accessory Powerº
in the Index.
Press and release the rear side of the button in the mini
console to open the sunroof. You can press the forward
side of the button to close the sunroof. Once the sunroof
is closed, press the forward side of the button to open
the sunroof to the vent position.
The sunroof is also equipped with a sunshade which you
can pull forward to block sun rays.

4-56 Trailer Wiring Harness
The light-duty trailer wiring is a six-wire harness
assembly. The optional heavy
-duty trailer wiring is an
eight
-wire harness assembly. The harnesses are stored
under the vehicle, along the passenger
-side frame
crossmember on two
-door vehicles or on the driver's
side corner frame rear crossmember on four
-door
vehicles. The heavy
-duty trailer wiring has a 30-amp
feed wire with an inline fuse located by the junction
block. See ªFuses and Circuit Breakersº in the Index.
Both harnesses have no connector and should be wired
by a qualified electrical technician. The technician can
use the following color code chart when connecting the
wiring harness to your trailer.

Dark Blue: Use for electric trailer brakes or
auxiliary wiring.

Red: Use for battery charging; it connects to the
starter solenoid (eight
-wire harness only).
Light Green: Back
-up lamps
(eight
-wire harness only).

Brown: Taillamps and parking lamps.

Yellow: Left stoplamp and turn signal.

Dark Green: Right stoplamp and turn signal.

White (Heavy Gauge): Ground wire.

White (Light Gauge): Auxiliary stoplamp.
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 doesn't bend or break, but
not so loose that it drags on the ground. Store the
harness in its original place. Wrap the harness together
and tie it neatly so it won't be damaged.
