To install the 7-way trailer connector on your 2004 Jeep Liberty you'll first need a 4-way connector. Use # 118524. It easily installs by plugging in behind both tail lights and includes a powered ModuLite to reduce the strain on your Jeep's wiring.

Once you have a 4-way you can install a 7-way. If the trailer doesn't have brakes you can use an adapter like # 37185 and just cap off the unused wires. If you want to power the trailer's brakes then you'll need to install a fully functioning 7-way using our # ETBC7 kit. This includes the 7-way plus everything you need to install an electric brake controller.

For a brake controller I suggest the Prodigy P3 # 90195. It's one of the top selling brake controllers on the market because of how reliable it is. Plus it has an easy to read LCD which makes it easier to use.

If you don't already have a trailer hitch receiver I suggest the Draw-Tite # 75128 which is confirmed to fit your Liberty.

You'll also need a ball mount and hitch ball. I've attached link of our selection of ball mounts for a 2 inch hitch receiver as well as an article to help you determine the correct rise or drop you may need. Once you choose a ball mount you can then choose a hitch ball to fit it.

One way to make choosing a ball mount easier is to go with an adjustable ball mount like the B&W Tow & Stow # BWTS10038B. It features the ability to be flipped under the hitch when not using it and will provide up to 5-1/2 inches of rise or 5 inches of drop.

For a pin and clip to fit you can use # PC3 or if you'd like to have a locking pin you can use # BX8858.

I've also included links to some articles on towing that you might find helpful.
