Trailer
Wiring
Harness
Your vehicle
may
have either a 5-wire or 7-wire
harness.
The light duty
trailer
wiring
is a 5-wire
harness
assembly
taped
and
bundled
at the left corner
of
the
vehicle
interior,
next
to the endgate. The harness has
no
connector,
and
you
should
have a qualified
service
person
wire
your
harness for
you.
It
must
be
routed
out
of
your
vehicle
and
attached
so
that
the
trailer or the
body
won’t
pull
it.
The heavy
duty
trailer
wiring
is a 7-wire
harness
assembly
consisting
of
a
5-wire harness and a 2-wire
harness
taped
together
and
stored
under
the
vehicle,
along
the
rear frame crossmember.
It
has a 30-amp
feed
wire
with
an inline fuse located by the junction block. See “Fuses
and
Circuit
Breakers”
in the Index.
Both
the
5-wire
harness
and
the
2-wire
harness
have
no connector and
should
be
wired by a qualified
service
person.
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.
