though bolts are there, do not assume they
are adequate for baseplate mounting. Always

1. Remove three bolts with a 10MM socket. Do
this to both sides of the vehicle. Set bolts
aside to be reinstalled later.
Vehicle Weight: The weight of this
vehicle is near the Class III, 5,000 lb. rating
limitations. Some models, depending on
options, may well exceed this 5,000 lb
rating. Be sure to conrm the weight of your
individual vehicle before towing. As of 1999
the Aventa® II is now 10,000 lbs. and either the
Aventa® II or the Aventa® LX tow bar must be
used for these applications.
Tow Bar Adapters are NOT to be used with
vehicles weighing over 5,000 lbs.
Installation Notes: The grille and
bumper are removed and reinstalled during
installation of the baseplate. Trimming of the
fascia 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 ling a hole slightly,
bending electrical rods and/ or bending end
plates.
The BX8869 Bulb & Socket Wiring Kit is
recommended for this vehicle.

Permanent Baseplate Safety Cable Installation
Permanent baseplate safety cables are strongly recommended when towing a vehicle with a tow bar.
The principle function of the permanent baseplate safety cables is to prevent the towed vehicle from
breaking loose in the event the connection between the frame of the towed vehicle and the baseplate
fails or becomes disconnected. The cables must be connected from the baseplate to the frame rail
or cross member of the vehicle’s frame. The illustrations below show the possible arrangements
recommended by Blue Ox®. Each permanent baseplate safety cable must have an adequate weight
rating for the towing system. The weight rating of the two (2) cables together will not qualify.
Do not mount the permanent baseplate safety cables against wires, hoses or brake lines.
These permanent baseplate safety cables should remain installed as long as the baseplate is
installed on the vehicle. Permanent baseplate safety cables are to be used in conjunction with,
and NOT a replacement for legally required safety cables attaching the towed vehicle to the towing
vehicle.
Notice To Baseplate Installer
1. It is YOUR responsibility to watch for:
• Oil cooler and air conditioner lines
• Electrical wires and hoses
• Missing parts or attaching points on the frame
** If the baseplate is improperly installed and is against a wire or hose, it could cause uid leaks or
electrical shorts some time after the actual baseplate installation.

parts and loose bolts before each towing trip. Be sure to use Loctite®Red on all bolts and tighten to the
recommended specications.
3. It is the owner’s responsibility to hook up all towing equipment per manufacturer’s instructions/
recommendations.
