Installing the EZ Light
wiring harness system
requires basic hand-tool skills. Failure to
understand how to install or operate this product
could result in property damage and/or personal
injury.
Installation Instructions
Driver side = Left side Passenger side = Right side
1) Find a convenient location to mount the control box that will allow the wiring harness to easily reach
the left and right tail lights. For instance, inside the spare tire well or behind an interior panel.
2) Gain access to the back of both the left and right tail light assemblies. This may be accomplished
from outside the vehicle or inside the vehicle depending on the make and model.
•Outside — remove the screws holding the tail light covers. Remove the covers and work the
taillight assemblies loose to expose the wiring.

Test and Operation Guide
While towing a vehicle equipped
with a remote brake system, it will be necessary to turn on the RV tail lights to provide
power to the braking system.
Have another person assist you when checking the tow system lighting for proper operation.
TEST BEFORE TOWING
1) When you have your towed vehicle hitched
and ready to tow, make sure the towed vehicle
electrical (umbilical) cable is connected
between your towed vehicle and RV.
2) Have your assistant sit at the driver seat in the
RV.
3) While standing at the rear of the towed vehicle,
have your assistant switch on the RV running
lights.
4) Both the RV tail lights and the towed vehicle tail
lights will light.
5) Have your assistant press the brake pedal in
the RV. RV brake lights and towed vehicle
brake lights will brightly light.
On towed vehicles with SEPARATE
BRAKE AND TURN lights, the controller will light
both BRAKE and TURN lights together. THIS
IS AN ENHANCED FEATURE that gives your
towed vehicle higher visibility to those driving
behind you.
6) Have your assistant release the brake pedal.
7) Have your assistant turn on the driver side turn
signal. The driver side turn light on the RV will
blink along with the driver side brake light
(and separate driver side turn light) on the
towed vehicle.
8) Have your assistant turn on the right turn
signal. The right turn light on the RV will blink
along with the right brake light (and separate
right turn light) on the towed vehicle.
