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...
