Hey Matthew, the first thing you need to add a 7-way to your 2022 Honda Odyssey is a 4-way since there isn't a direct fitting 7-way available for your vehicle. So for a 4-way you would want the Tekonsha part # 118781 which is very easy to install and has the most reliable converter box.

Now to convert it to a 7-way all you need is the # 37185. If your trailer has brakes that you need to activate you would need to go a different route though. Does your trailer have brakes?

Hey Matthew, did you find the 4-way and 7-way setup worked for your Honda Odyssey? I'm asking because your experience could help others looking to do the same.
