Installation Instructions
BX7302 Ambassador Tow Bar
Tow Bar Installation
1. Hold the Tow Bar in position, with its tabs aligned inside the 
baseplate tabs and insert the pins. Insert quick pins into the 
baseplate pins to hold them in position.
2. Install safety cables or chains and adjust coupler.
3. Do not substitute other devices if the pins are lost.
4. DEALER OR INSTALLER: BE CERTAIN USER RECEIVES 
INSTRUCTION SHEETS.
Notice
1. Blue Ox Tow Bars are designed for the coupler to be parallel 
to the ground when it is attached to the towed and towing  
vehicles. If the Tow Bar coupler is at an angle, damage or 
accident may occur.
2. Blue Ox Tow Bars are designed to tow manual transmission 
cars or automatics equipped with a transmission pump, drive 
shaft disconnect or half shaft disconnect.
3. The transmission should be placed in neutral to tow. (Refer 
to your vehicle's owners manual for details)
4. Unlock the steering wheel to allow the front wheels of the 
towed vehicle to “track”.
5. Be sure front end of the car being towed is properly aligned.
6. The use of safety cables or chains is REQUIRED BY LAW.  
Blue Ox Model BX8805 (5ft) or BX8806 (6ft) Safety Cables 
are recommended. The shorter BX8805 is normally best.
7. Adjust the coupler for proper fi t to the ball (see coupler fi t  
adjustment). For added security, place a lock, pin or bolt 
through the hole provided in the coupler locking lever.
8. Check clearance between vehicles in while turning.
9. Most states require rear lighting on the towed car. A BX8869, 
BX8811 or BX8847 Wiring Kit is recommended.
10. Prior to a towing trip, check to be sure all towing accessories 
and attachment points are secure. Check for cracked 
welds and loose bolts. This is important on all occasions 
but particularly on a new installation, when they should be 
checked just prior to initial towing and again after 100-200 
miles of towing.
11. Do Not Back Up when towing. Backing up may damage the 
Tow Bar assembly or the towed car’s chassis. 
12. Avoid sharp turns and rough terrain. Check installation after 
an unusual event and periodically on long trips.
13. Do not use towed vehicle for storing luggage, etc.; you may 
exceed the towing capacity of the Tow Bar.
 WARNING: Ensure that your towing vehicle is of adequate 
size to properly control your towed vehicle. The weight and 
braking capacity should be large enough to handle both 
vehicles in an emergency situation. Check your towing 
vehicle manufacturers recommendations for towing, hitch 
load, and braking capacities. The hitch, ball, motorhome 
chassis, and safety cables (each individual cable) need to be 
rated at a minimum for the weight of the vehicle being towed.

1. Using the cable hooks, attach the cables to a solid part of the 
chassis of the towed vehicle or to the baseplate convenience 
loops. Slip the end of the hook through the neoprene keeper 
to prevent the hook from unhooking. (See Fig. 3) NOTE: It is 
recommended to have permanent chains that connect the 
convenience loops to the frame of the car. (See Fig. 2)
2. Wrap each cable once or twice around their respective tow bar 
leg and cross them under the coupler area. (See Fig. 1)
3. Using the cable hooks, attach the opposite ends of the cables to 
a solid part of the chassis of the towing vehicle if at all possible.  
Slip the end of the hook through the neoprene keeper to prevent 
the hook from unhooking. (See Fig. 3)
4. Adjust slack so that the cables cannot touch the ground or become caught beneath the ball. If either of these things happen, 
the cables may become damaged and ineffective. DO NOT USE 
DAMAGED CABLES!
