Step 1
Locate vehicle battery on the driver side under the hood and disconnect the negative battery terminal.
Step 4
Locate a suitable mounting point on the driver side between the rear post and the wheel well and route the harness to this location.
Note: Be sure the harness will not pinch or bind when turning.
Check for miscellaneous items that may be hidden behind or under any surface before drilling to avoid damage and / or personal injury.
Step 2
Locate the vehicle taillight wiring harness
connector. It will be connected to the vehicle
7-way trailer connector, mounted to the hitch
or bumper at the rear of the vehicle. The
connector will be similar to that on the
custom wiring harness extension.
Separate the 7-way connector from the
vehicle wiring harness by carefully releasing
the gray locking clip and gently pulling the
connector apart while holding down on the
connector locking latch.
Step 3
Position the paired extension harness ends
between the separated connectors. Insert
the longer of the paired connectors into the
vehicle wiring harness connector. Make
sure the connectors are fully inserted with
locking tabs in place.
Insert the shorter of the paired connectors
into rear of the factory 7-way socket. Make
sure the connectors are fully inserted with
locking tabs in place. Return the locking
clip to it's original position.
Step 5
Using a hole saw, drill a 2-1/8" hole in the
desired location in the sidewall. Using a file,
smooth the edges of the hole to prevent
abrasion of the harness or connector.
