  1. 1

    Read your vehicle owner's manual. Different makes and models will require different tow bars. The manual will detail the type of tow bar required, the amount of weight the vehicle is capable of towing, and, in some cases, will also offer basic mounting instructions.

  2. 2

    Find the mounting points: The complexity of this task depends on the make and model of the vehicle. In some cases, you will have to remove part of the boot trim inside the vehicle. You might also need to remove the side panels. Vehicles made after September 1998 have tow bar mounting holes built into the chassis, which makes the fitting process much easier.

  3. 3

    Mount the tow bar. Using the nuts and bolts included with the tow bar, securely fasten the tow bar mount onto the chassis of the vehicle at the mounting points. Use a wrench to ensure it is tightly fastened.

  4. 4

    Don’t forget to wire correctly. Wire a female-end harness on the towing vehicle to a male-end harness on the vehicle or trailer being towed. Newer vehicles may require a vehicle-specific plug-in electrical kit, Talk to the dealer when buying your tow bar, or refer to the owner's manual. This wiring is essential to make the vehicle or trailer being towed street legal.
