WIRE INSTALLATION TIPS
By law, trailer lighting must be connected into the tow vehicle's wiring system
to provide 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.
TRAILER CONNECTORS
Various styles of connectors are available with four to seven pins to allow
transfer of power for the lighting as well as auxiliary functions such as
electric trailer brake control, backup lights etc. Choose a connector that has
the required number of pins for the functions required.
The male end is mounted on the vehicle side and the female on the trailer side.
4 WAY CONNECTORS
Flat, molded connectors are available allowing the basic hookup of the three
lighting functions and ground. Round 1-1/4" knock-out style can be permanently
mounted directly onto all Hidden Hitch products or onto a separate plug mounting
bracket. This provides a clean installation and avoids the potential problems
associated with leaving a plug dangling from the rear of the towing vehicle.
6 WAY TRAILER CONNECTORS
Round 1-1/4" diameter metal connectors are available that allow 1 or 2
additional functions such as back up lights and electric brakes. These can be
mounted on all Hidden Hitch products.
7 WAY CONNECTORS
Additional pins for auxiliary power, trailer battery charging etc. are available
using larger 2" diameter, round connectors. Typically these are needed for
larger trailers and can be mounted directly in the bracket mounted on every
Class III and IV Hidden Hitch.
