The seven-wire harness contains the following
trailer circuits:
• Yellow: Left Stop/Turn Signal
• Dark Green: Right Stop/Turn Signal
• Brown: Taillamps
• White: Ground
• Light Green: Back-up Lamps
• Red: Battery Feed*
• Dark Blue: Trailer Brake*
*The fuses for these two circuits are installed in
the underhood electrical center, but the wires
are not connected. They should be connected by
your dealer/retailer or a qualified service center.
If you are charging a remote (non-vehicle) battery,
press the tow/haul mode button located at the
end of the shift lever. This will boost the vehicle
system voltage and properly charge the battery. If
the trailer is too light for tow/haul mode, you
can turn on the headlamps (Non-HID only) as a
second way to boost the vehicle system and
charge the battery.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat
during severe operating conditions. See Engine
