Curt Custom Fit Vehicle Wiring - Trailer Hitch Wiring - C55369 Review Video

The hitch that you referenced the Curt #13051, is indeed a class III hitch that is confirmed as a fit for your 2004 Jeep Grand Cherokee. I have included a video of this installation for your reference. Since your Cherokee does not have any existing…

Since you do not have the tow package I am assuming you do not have a factory trailer connector. In that case I would recommend you get a Curt T-Connector Custom Fit Vehicle Wiring #C55369. This is the recommended wiring harness for the 1999-2004…

The difference between the Class II and Class III hitches has to do with their Gross Trailer Weight (GTW), their Tongue Weight (TW), and their Hitch Receiver Size. Class II trailer hitch receivers have a 1-1/4 inch receiver and can be rated up to…
