2006 Nissan Towing Guide 8 BREAKAWAY SWITCH
On a trailer with electric brakes, a breakaway switch can automatically activate the trailer
brake system if the trailer becomes separated from the tow vehicle. Should the trailer
become detached, a breakaway switch may help prevent the trailer from wandering into
another lane and will bring it to a safer stop with less damage.
A breakaway switch relies on the power of a trailer battery, so make sure it is not
discharged. Never use the breakaway switch to “park” the trailer on a grade. The battery
would eventually discharge and release the brake, allowing the trailer to roll.
Be sure to leave enough slack in the tether on the breakaway switch to turn corners
without binding. If not, the electric trailer brakes will lock-up and not release.
See your trailer manufacturer for proper installation of a breakaway switch that is
compatible with your trailer braking system.
TRAILER LIGHTS
Trailer lights should comply with all applicable federal, state, and local regulations, and
should be in proper working order at all times. A trailer’s taillights, stoplights, and turn
signals must be wired* into the tow vehicle’s electrical system. Many trailers use the same
filament of a dual-filament bulb for both stoplights and turn signals. The second filament is
used for the trailer’s taillights. All Nissan vehicles utilize separate filaments for each
function. Direct splicing of this type of trailer lighting may cause damage to your vehicle’s
electrical system and malfunction of the trailer lighting. When connecting your Nissan
vehicle to this type of trailer lighting system, a 3-wire to 2-wire power converter** must be
used. A power converter of this type creates only minimal additional demand (draw) on the
vehicle lighting circuits to power the trailer lighting.
Always check for correct operation of the turn signals, stoplights, and taillights every
time you connect a trailer for towing. Never replace vehicle fuses with fuses of a higher
amperage rating than the original.
NOTE – Improper or poor quality trailer harness wiring may affect your vehicle’s electrical
system. Use only a Nissan approved wiring harness, or consult your dealer or a
professional supplier of towing equipment for compatible equipment.
*See the SPECIFICATIONS section of this guide for wiring harness information specific to your
vehicle.
**Armada, Frontier, Pathfinder, Titan, and Xterra vehicles are pre-wired for trailer lighting and do not
require a converter.
