For Chevrolet, GMC or Ram Pickup Trucks
with the factory trailer towing package only
CONNECT NEW TRUCK BOX
HARNESS TO TRUCK
Locate the factory wiring hitch harness under or behind the
rear bumper of your truck. Disconnect the existing connec-
tors as shown below. Note that there is a locking tab that
needs to be depressed to disconnect the harnesses. Connect
your Weather Guard® Hitch Harness between the factory
connectors as shown below.
Tuck in and secure the Weather Guard® Hitch Harness to the
bumper, bed, or existing factory wiring harness using zip ties.
ROUTE HARNESS TO TRUCK BED
Route the new harness between the rear bumper and the
knock out hole in the bulkhead of the truck bed. It is usually
easiest to follow the path of an existing wiring harness along
the frame of the truck (recommend driver side). Secure the
new harness to the truck in a few locations using the zip ties
supplied.
ROUTE HARNESS INTO TRUCK BOX AND
CONNECT
Remove the knock-out plug from the bulkhead of the truck
bed, feed the harness end into the truck bed and then
through the grommet in the side of the truck box.
