Jeep Wrangler: Towing Requirements / Towing Requirements — Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the
trailer size, stoplights and turn signals on the
trailer are required for motoring safety.
The Trailer Tow Package may include a four- and
seven-pin wiring harness. Use a factory
approved trailer harness and connector.
NOTE:
Do not cut or splice wiring into the vehicle’s
wiring harness.
The electrical connections are all complete to
the vehicle but you must mate the harness to a
trailer connector. Refer to the following
illustrations.
NOTE:
Disconnect trailer wiring connector from the
vehicle before launching a boat (or any other
device plugged into vehicle’s electrical
connect) into water.
Be sure to reconnect once clear from water
area.

Do not interconnect the hydraulic brake
system or vacuum system of your vehicle
with that of the trailer. This could cause inadequate
braking and possible personal injury...
Before setting out on a trip, practice turning,
stopping and backing the trailer in an area away
from heavy traffic.
If using a manual transmission vehicle for trailer
towing, all starts must be in FIRST gear to avoid
excessive clutch slippage...
Other information:
To maintain the appearance of your vehicle's
interior trim and top, follow these precautions:
Do not run a fabric top through an automatic
car wash. Window scratches and wax
build-up may result.
Avoid leaving your vehicle unattended with
the top down, as exposure to sun or rain may
damage interior trim...
Child restraint systems are designed to be
secured in vehicle seats by lap belts or the lap
belt portion of a lap/shoulder belt.
WARNING!
Improper installation or failure to properly
secure a child restraint can lead to failure
of the restraint...
