CAUTION
Verify what is behind any surface prior to drilling to
avoid damage to the vehicle and/or personal injury.
Do not drill into any exposed surfaces.
4. Using the 7-way end as a guide, mark the mounting
hole locations with a center punch
i
and then drill
four 3/32” holes as marked.
NOTE
Use rust-proof coating in drilled areas to prevent
future rusting (not provided).
CAUTION

avoid damage to the vehicle and/or personal injury.
Do not drill into any exposed surfaces.
5. Route harness thru mounting hole and connect
the 7-way end to the harness
jk
. Using the
4 self- tapping screws, mount the 7-way harness
to the vehicle surface.
WARNING
All connections must be complete for the Trailer
Tow Harness to function properly. Test and verify
installation with a test light or trailer once installed.
NOTE
On some vehicles you may need to add a fuse or
relay (not provided) to complete all of the functions
going to the 7-way. Consult your owner’s manual for
locations.
6. Secure the harness to the vehicle, using the cable
ties provided.
WARNING
Route the wire being careful to avoid any hot pipes,
heat shields, the fuel tank or any other points that
may pinch or break the wire.
WARNING
When plugging in the wiring harnesses and other
connectors into 7 way connectors at the rear of the
vehicle use dielectric grease to seal the connection.
This will keep moisture from compromising the
connection and potentially setting off an error code
on brake controls and preventing plug corrosion.
If an error code is found, the error codes on the
brake controls will reset to normal after the
connectors are disassembled and dried out.

(approximately 4” or more) that will be needed in
step 5. In addition, make sure that the trailer’s wire
harness has adequate length to reach this point
and that you have at least 5” of clearance behind
the mounting surface for installation
