Installation Instructions
BX3776
1. Blue Ox®towing products and accessories
are intended to be installed by Blue Ox®
Dealers who are familiar with our products and
have the equipment and knowledge to do “fit
work.” When necessary, Blue Ox®Dealers can
be found at www.blueox.us or by contacting
our Customer Care Department at
[phone].
2. Many Blue Ox®Baseplates are designed to
use existing holes and hardware to mount
the baseplate to the towed vehicle. Even
though bolts are there, do not assume they
are adequate for baseplate mounting. Always
use hardware supplied in the hardware kit
or existing hardware specified in the
Baseplate Towing Installation Instructions.
Serial Number
Confirm the towability and pre-towing
procedures for your vehicle with
the owner’s manual or contact the
vehicle’s manufacturer for specific
towing procedures. You can also
contact REMCO for additional towing
information at 1(800)228-2481.
Please read BOTH these Installation Instructions and the General Towing
Instructions before attempting to install or operate this equipment.
!
Failure to read and follow these instructions
could result in separation of the towed vehicle
from the tow bar, causing property damage,
loss of towed vehicle, personal injury or death.

Important:
Use only genuine factory replacement parts on your baseplate. Do NOT substitute homemade or non-typical parts. If a bolt
is lost or in need of replacement, for your safety and the preservation of your baseplate, be sure to use a replacement bolt of
the same grade (In most cases it will be Grade 5, please reference the parts list above). Replacement parts may be ordered
through your nearest Blue Ox® Dealer or Distributor.

1. Using a flat screwdriver, remove four plastic
push pins from the radiator cover driver’s side
and with a 10MM socket, remove one bolt
from the outside edge (grey arrow). Set push
pins and bolt aside to be reinstalled later.
Vehicle Weight:
Motorhome mount tow bars are recommended for
use with this baseplate. Due to the design of the
removable tabs, the RangeFinderII, Adventurer,
and Ambassador tow bars can not be used. The
Acclaim tow bar may be used, but will not fold and
store on the front of the vehicle. Adapters, except
the BX8833 and BX88151, can not be used with
this baseplate.
Installation Notes: The radiator cover,
fascia, washer reservoir and vent tube are
removed and reinstalled during installation of
the baseplate. Drilling is required. Trimming
of the lower frame support webbing is
required.
The dimensional variations between otherwise
identical vehicles can be considerable.
While the baseplate was designed for easy
installation, it may be necessary to tailor the
baseplate slightly to compensate for auto
manufacturer’s tolerances. These minor
adjustments may include filing a hole slightly,
bending electrical rods and/ or bending end
plates.
The BX8869 Bulb and Socket Wiring Kit is
recommended for this vehicle.
