Trailer Hitch, Wiring Harness, Transmission Cooler and Suspension Enhancement for 2012 Honda Odyssey


Hi, I have a 2012 Honda Odyssey and I am interested in installing a towing hitch. I initially searched on Hondas OEM site and its quite expensive. I was wondering exactly what I needed to purchase to make it all work right and there were so many options on your website. What are the essentials that you would recommend? The hitch, harness? Is an oil or transmission cooler mandatory? Do I need to get the improved suspension springs as well? Any advice would be greatly recommended. Thanks

Let's begin with the trailer hitch. The Curt Class III trailer hitch, part # C13068 offers the best ground clearance of the available Class III hitches so that's the hitch I'd recommend. For the trailer wiring harness, I'd go with the # 118521 from Tow Ready. You'll also need a ball mount like # 2753 and a trailer ball. For a 1-7/8 inch ball, use # 19260 or # 63845 for a 2 inch ball.

In the owner's manual, Honda strongly recommends installing a supplemental transmission cooler, like # D13503. I'll link you to a video showing the cooler being installed on a 2013 Odyssey. The procedure would be the same on your vehicle. Adding a transmission cooler is inexpensive insurance to protect your transmission from overheating.

A suspension enhancement product like the Timbren # THROD2 will provide extra support for the rear suspension of your Odyssey when the cargo area is loaded or when the tongue weight of a trailer is compressing your rear suspension. This will prevent the rear end sag, which interferes with the aim of your headlights as well as braking and steering response. The thing I like about the Timbren system is that it will NOT affect the ride of the vehicle unless the rear suspension is under load.
