TRAILER WIRING

Wiring the vehicle for towing is fairly easy. There are a number o

wiring kits available and these should be used, rather than trying to

your own.

All trailers will need brake lights and turn signals as well as tail I

and side marker lights. Most areas require extra marker lights for o\. Also, most areas have recently required back-up lights for t

and most trailer manufacturers have been building trailers with back
lights for several years.
Additionally, some Class I, most Class II and just about all Cla.
and IV trailers will have electric brakes. Add to this number an act
series wire, to operate trailer internal equipment or to charge the t
battery, and you can have as many as seven wires in the harness.
Determine the equipment on your trailer and buy the wiring kit ne
sary. The kit will contain all the wires needed, plus a plug adapter sf
includes the female plug, mounted on the bumper or hitch, and the

color coding-of the wires is usually standard throughout the industry.

One point to note: some domestic vehicles, and most imported vehicles,

have separate turn signals. On most domestic vehicles, the brake lights

and rear turn signals operate with the same bulb. For those vehicles with

separate turn signals, you can purchase an isolation unit so that the

brake lights won't blink whenever the turn signals are operated, or, you

can go to your local electronics supply house and buy four diodes to

wire in series with the brake and turn signal bulbs. Diodes will isolate

the brake and turn signals. The choice is yours. The isolation units are

simple and quick to install, but far more expensive than the diodes.

The diodes, however, require more work to install properly, since they

require the cutting of each bulb's wire and soldering in place of the

diode.

One, final point, the best kits are those with a spring loaded cover on the

vehicle mounted socket. This cover prevents dirt and moisture from corrod-

ing the terminals. Never let the vehicle socket hang loosely; always mount it

securely to the bumper or hitch.
