Refer to the aftermarket electric

controller. The wire colors on the
brake controller may be different
from the vehicle. The electric trailer
brake controller should be installed

center. If equipped, there are four blunt cut
wires inside the front driver side

necessary to have a technician
connect the 12-volt power to the
engine compartment fuse block.

working at the beginning of each
trip, and periodically on longer trips.

Trailer
When properly connected, the trailer
turn signals will illuminate to indicate
the vehicle is turning, changing
lanes, or stopping. When towing a
trailer, the arrows on the instrument
cluster will illuminate even if the
trailer is not properly connected or
the bulbs are burned out.
