The hitch should be appropriate for the type of trailer being towed. The most common is the familiar ball hitch although receiver hitches are sometimes found on Honda vehicles. Honda does not provide hitches at the time of purchase; they must be purchased and installed separately. The hitch mounts must be securely attached to the body of the car. Never use a hitch attached only to the bumper and never use a hitch designed for temporary use.
When you've determined the hitch that you'll need, follow the manufacturer's installation instructions exactly, especially when it comes to fastener torques. The hitch will subjected to a lot of stress and good hitches come with hardened bolts. Never substitute an inferior bolt for a hardened bolt.
