an integrated trailer brake controller,
a trailer brake controller needs to be
installed on the vehicle if the trailer
has electric brakes. The brake
controller should be installed by your dealer or a qualified service
center. If equipped, wiring
provisions for an aftermarket electric
trailer brake controller are included
with the vehicle as part of the trailer
wiring package. The harness
contains the following circuits:

coding of the electric trailer brake
controller. The wire colors on the
brake controller may be different
from the vehicle. The fuse for the
electric trailer brake circuit is in the
engine compartment fuse block, but
the wires may not be connected.
They should be connected by your
dealer or a qualified service center.
