Step 1
Locate the vehicle battery. Look up the
battery location in the owner's manual of
your vehicle. Disconnect the negative battery
terminal. Be sure to fasten this wire down
and away from the battery when completing
the installation process.
Step 2
Locate the electrical junction box at the
rear of the vehicle between the frame rail
and the spare tire on the driver side. Locate
the driver-side taillight harness. You may
need to trace the wires back to the taillight.
Separate the connectors, taking care not
to damage the locking tabs. Install the
custom RV harness with the yellow wire
in-between the factory harness.
Step 3
In the same junction block is the passenger-
side harness. You may need to trace the wires
back to the taillight. Separate the connectors,
taking care not to damage the locking tabs.
Install the custom RV harness with the green
wire in-between the factory harness.
Step 4
Locate a grounding point near the box such as an existing screw or bolt in the frame
of the vehicle or drill a 3/32” pilot hole. The area should be free from rust, dirt, and
paint (Use abrasive pad/paper to remove rust and paint). Secure the white ground
wire with the ring terminal on the existing fastener or with the provided ground screw.
WARNING
Check for miscellaneous items that may be hidden behind or under
any surface before drilling to avoid damage and / or personal injury.
NOTICE
Once the custom wiring harness is installed, verify that the harness is functioning
by attaching the 4-flat to any vehicle with functioning trailer lights. The taillights
on the tow vehicle should function along with the taillights on the towing vehicle.
