| Wire Installation
Tips |
|
By law, trailer lighting must be connected into the tow
vehicle's wiring system to provide the trailer running lights, turn signals
and brake lights. This is accomplished by tapping into the tow vehicle's
electrical harness to transfer power to the trailer wiring system. Connectors
are used between the two to allow disengagement when not towing. |

|
Various styles
of connectors are available with four to seven pins to allow transfer for the
lighting as well as auxiliary functions such as electric trailer brake
control, backup lights etc. Choose a connector that had the required number of
pins for the functions required. The male end is mounted on the vehicle side
the female on the trailer side.

Connectors |

Flat, molded
connectors are available allowing basic hookup of the three lighting functions
and ground. Flat 4-way plugs can be permanently mounted directly onto all
trailer hitches by use of mount part number 18144. This
provides a clean installation and avoids the potential problems associated
with leaving a plug dangling from the rear of the towing vehicle.

Round
1-1/4" diameter metal connectors are available that allow 1 to 2
additional functions such as back up lights and electric brakes.

Additional
pins for auxiliary power, trailer battery charging etc. are available using
large 2" diameter, round connectors. Typically these are needed for
larger trailers and can be mounted directly in the bracket mounted on every
Class III, IV and V hitch.
