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.

If you carry reflective triangles, you can set one up at
the side
of the road about 300 feet (100 m) behind
your vehicle.
Jump Starting
If your battery has run down, you may want to use another
vehicle and some jumper cables
to start your vehicle. But
please follow the numbered steps to do it safely.
1
Batteries can hurt you. They can be dangerous
because:
They contain acid that can burn you.
0 They contain gas that can explode or ignite.
They contain enough electricity to burn you.
If you don’t follow these steps exactly, some
or all
of these things can hurt you.
NOTICE:
Ignoring these steps could result in costly damage
to your vehicle that wouldn’t be covered by
your warranty.
Trying to start your vehicle by pushing or pulling
it won’t work, and it could damage your vehicle.
I. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
I NOTICE:
If the other system isn’t a 12-volt system with a
negative ground, both vehicles can be damaged.

can reach, but be sure the vehicles aren’t touching
each other.
If they are, it could cause a ground
connection you don’t want.
You wouldn’t be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly
on both vehicles involved in
the jump start procedure. Put an automatic
transmission
in PARK (P).
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or accessory power outlets. Turn
off all lamps
that aren’t needed as well
as radios. This will avoid
sparks and help save both batteries. In addition, it
could save your radio!
NOTICE:
I I
If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
4. Open the hoods and locate the batteries. Find the
positive
(+) and negative (-) terminals on each battery.
Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use a flashlight
if
you need more light.
Be sure the battery has enough water. You don’t
need to add water to the Delco Freedom@ battery
installed in every new
GM vehicle. But if a
battery has filler caps, be sure the right amount
of fluid is there.
If it is low, add water to take care
of that first. If’ you don’t, explosive gas could
be present.
Battery fluid contains acid that can burn you.
Don’t get
it on you. If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.

missing insulation. If they do, you could get a shock.
The vehicles could be damaged too.
Before you connect the cables, here are some basic
things
you should know. Positive (+) will go to
positive
(+) and negative (-) will go to negative (-)
or a metal engine part. Don’t connect positive (+) to
negative (-) or you’ll get a short that would damage
the battery and maybe other parts
too.

6. Connect the red
positive
(+) cable to the
positive
(+) terminal of
the vehicle with the
dead battery.
7. Don’t let the other end
touch metal. Connect
it to
the positive (+) terminal
of the good battery.
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engines are running.

negative
(-) cable to
the good battery’s
negative
(-) terminal.
Don’t
let the other end
touch anything until the
next step. The other end
of the negative
(-) cable
does not
go to the dead
battery. It goes to a
heavy unpainted metal
part of the vehicle with
the dead battery.
9. Make your last connection away from the battery,
to the engine block, frame or other unpainted metal
parts
of your vehicle.
The electrical connection is just as good there, but
the chance of sparks getting back to
the battery is
much less.
10. Now start the vehicle with the good battery and run
the engine for a while.
11.
Try to start the vehicle with the dead battery. If it
won’t start after a few tries, it probably needs
service.
12. Remove the cables in reverse order to prevent
electrical shorting. Take care that they don’t touch
each other or any other metal.

Every new vehicle has a Delco Freedom@ battery. You
never have to add water to one of these. When it’s time
for a new battery, we recommend a Delco Freedom
battery. Get one that has
the replacement number shown
on the original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days
or more, take off the black, negative
(-) cable from
the battery. This will help keep your battery from
running down. Also,
for your audio system, see “Theft-Deterrent
Feature” in the Index.
Bulb Replacement
For any bulb changing procedure not listed in this
section, contact your
GM dealer service department.
Before replacing any bulbs, make sure all lamps are
off
and the vehicle is not running. See “Replacement Bulbs”
in the Index.
Halogen Bulbs
Batteries have acid that can burn you and gas
that can explode.
You can be badly hurt if you
aren’t careful. See “Jump Starting” in the Index
for tips on working around a battery without getting hurt.
Contact your dealer to learn how
to prepare your vehicle
for longer storage periods.
I A CAUTION:
I
Halogen bulbs have pressurized gas inside and
can burst if you drop or scratch the bulb.
You or
others could be injured. Be sure to read and
follow the instructions on the bulb package.
