Step 8
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
(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.

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.

Route the 4-flat wire above the rear drive line
and suspension mounts and the body. Zip tie
in place, making sure the wires will not come
into contact with moving or hot objects.
Step 10
Route the 4-flat wire into the plastic
underbody pan just to the rear of the
fuel tank. Route along the fuel tank
between the tank and the driver-side
sub frame to the rear of the front tire.
Step 11
From the driver-side engine compartment,
use the fish wire between the inner fender and
the exterior fender to route the 4-flat up to
the engine compartment. Locate the end of
the fish wire just behind the inner fender /
wheel well and attach to the fish wire. Pull
to the top side of the engine compartment.
