Hitch, Wiring and Ball Mount to Equip 2003 Honda Odyssey and 2015 Toyota Prius for Towing

Expert Reply:

We can help you get your two vehicles, the 2003 Honda Odyssey and the 2015 Toyota Prius, ready to tow your Yakima Rack-and-Roll trailer, whether it is the 66-inch model # Y08106 or the 78-inch model # Y08107. Let's start with hitches for the cars.

For your 2003 Honda Odyssey both 2-inch and 1-1/4-inch hitches are offered. To keep things simple and compatible with the Prius I suggest the 1-1/4-inch Class II hitch # C12031 which offers no-drill installation; it comes with all required hardware. For a 4-pole wiring harness kit for the trailer lights you can use # 118336 which offers plug-in installation.

For your Prius you can use 1-1/4-inch Class I hitch # 24847 and wiring harness # C56147.

You are correct that the height of the trailer coupler requires a hitch ball height of 22-inches in order to keep the trailer level when hitched. This is important for good handling.

Now for a ball mount. The two hitches will have installed heights that are only 2-inches different from one another; 13-inches above ground for the Odyssey and 11-inches above ground for the Prius. You can probably use the same ball mount for both cars without issue. The most height rise available in a Class I ball mount is 5-3/8-inches, part # C45028. This ball mount will work in both hitches. You can use hitch ball # C40018 and pin and clip kit # F-4.
