Do not exceed product rating or tow vehicle lamp load rating, whichever is lower.
The battery connection must be fuse-protected, 15-amp max. Exceeding
the product rating can cause loss of warranty, overheating and potential fire.
Do not lay tools across the positive terminal (typically labeled with red covers or a red “+”
symbol). This can cause a ground to short causing sparks, and / or electrical shocks.

Periodic inspection of all wires and connections should be performed
to ensure there is no visible damage or loose connections.

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.
If installing on a Honda Pilot,
proceed to step 2A.
If installing on a Honda Passport,
proceed to step 2B on page four.
Step 2A - Pilot
Open the rear hatch, fold down the
rear seats and remove the floor coverings.
Step 3A - Pilot
Remove the spare tire tool kit access panel
on the driver side and remove the jack.
Step 4A - Pilot
Remove the access panel to the fuel funnel.

Step 5A - Pilot
Remove the rear seat trim to release
the fasteners by lifting up at the bottom
and pulling to the rear of the vehicle.
Step 6A - Pilot
Unfold the rear seats. From the driver-side
third row rear seat, remove the elastic band
that is attached to the lower seat, wrapped
around the seatbelt latch (female side).
Step 7A - Pilot
Reach between the back of the seat and
the seat and pull towards the front of the
vehicle to reveal a grommet with several
wires. Pull this grommet out.
Step 8A - Pilot
Install the red 10-amp fuse from the bag kit
into the fuse holder on the factory harness. Pull
back the carpet and route the white connector
end between the vehicle floor pan and the
driver-side wall. Route the harness in front of
the jack mount and behind the access panel.

Step 9A - Pilot
From the funnel access, reach up and to
the rear and find the mating housing that
connects to the custom harness. If the housing
is already connected to a harness, you will
need to disconnect this housing (used for the
backup sensor). Install the custom wiring
harness to the vehicle wiring harness. Make
sure the connectors are fully inserted with
locking tabs in place.
NOTICE
If you need to disconnect the backup sensor
you will need to reconnect it to the single wire
connector on the custom wiring harness. This
allows the backup sensor to still function.
NOTICE
If gaining access to the harness is difficult due
to physical limitations, follow steps 3B and 4B
for the Passport to attach the custom wiring
harness to the factory harness in the Pilot.
Step 10A - Pilot
Route the round housing over to the
grommet found under the third row seat
and feed the round housing down through
this hole. The USCAR plug will fit through
the oval opening sideways.
Proceed to Step 11 on page six to complete
the installation for the Honda Pilot..
Step 2B - Passport
Open the rear hatch and storage hatch
to expose the spare tire. Locate the two
locking rings in the storage tray and
loosen to remove the tray.
Remove the spare tire
from the storage hatch.

Step 3B - Passport
Using a trim tool, remove the skid plate at the
rear of the vehicle. Using a small flat head
screw driver, release the cover on the upper
cargo hook. Remove the 8mm bolt behind
the cover. Using a flat head screw driver, lift
the lower cargo hook and open the access to
expose a large Phillips-head screw.
NOTICE
The Phillips-head screw can be troublesome.
Use an impact screwdriver to prevent damage
to the screw when removing.
Step 4B - Passport
Use a panel trim removal tool to release
the driver-side panel and pull open the
panel to expose the factory harness.
Step 5B - Passport
Use the panel trim removal tool to
remove the push fastener securing
the floor covering in place (the access
hole below the side storage bin).
Pull the carpet back from the driver side
to the passenger side. Use the trim tool
to remove the plastic cover exposing the
electrical passing through the grommet.

Step 6B - Passport
Install the red 10-amp fuse from the
bag kit into the fuse holder on the factory
harness. From the access hole below the
side storage bin on the driver side, run the
white connector end up to the factory harness
plug. If this housing is already connected to
a harness, disconnect this housing (used for
the backup sensor). Install the custom wiring
harness to the vehicle wiring harness. Make
sure the connectors are fully inserted with
locking tabs in place.
NOTICE
If you need to disconnect the backup sensor
you will need to reconnect it to the single wire
connector on the custom wiring harness. This
allows the backup sensor to still function.
Step 7B - Passport
Run the other end of the harness under
the carpet and through the grommet hole
(the USCAR plug will fit through the oval
opening sideways).
Proceed to Step 11 to complete the
installation for the Honda Passport.
Step 11
From under the vehicle, determine the
7-way mounting location and mount the
7-way socket connector. Route the wiring
in the center of the vehicle (above the spare tire
on the Pilot). Secure with zip ties as needed
and plug into the 7-way socket connector.
Step 12
From inside the vehicle use a cutting tool to carefully cut the grommet, allowing a large enough
opening for the custom wiring harness to go through and allows the grommet to be pushed back
into place in the body of the vehicle. Use the tube of silicon to seal around the custom wiring harness.

Step 13
Locate a flat spot on the floor board of the
vehicle. Adhere the black converter box using
the provided double-sided tape.

Locate a suitable grounding point near
the connector such as an existing screw
with nut in the vehicle frame or drill a 3/32"
pilot hole for the provided screw. The area
should be free of rust, dirt and paint. Secure
the white ground wire using the ring terminal
and provided screw.
CAUTION
Check for miscellaneous items that may be
hidden behind or under any surface before
drilling to avoid damage and / or personal injury.
Step 14
In the engine compartment, locate the fuse
panel next to the brake fluid reservoir. Remove
the cover and install the two 20-amp (yellow)
fuses in the three and eleven locations, and the
30-amp (pink) fuse in location two.
Step 15
Reinstall all items removed during harness install, and reconnect the negative battery terminal.
NOTICE
Once the 12 volt power wire is connected to the harness verify that the harness is functioning
by attaching the battery and testing with a test light, 4-flat tester, or a functioning trailer.

Verify the inline fuse is good. Check the grounding location using a test light.
Attach the clip end of the test light to the ground location using the probe end
of the test light on the power wire from the battery.
Make sure the surface around the ring terminal is raw or bare metal.
