33. Connect the Wire Lead from the two

Side Running Lights (24) to the Brown Wire on

each side of the Trailer. Then, insert Wire Clips

along the entire length of the Side Rails of the

Trailer to hold down the Wiring Harness.

34. Run the Yellow/Brown Wires to the

Left Tail Light (28L).

Strip the ends of the Wires about 3/4″.

NOTE: Only a qualified technician should perform

the electrical service that may be needed to

enable your particular make/model vehicle to

power the Trailer’s 12 volt DC lighting system.

This is beyond the scope of this manual.
