Where are the wires on my vehicle(2005 Mazda-Tribute)

–Maggie 2/28/2014 4:45:32 PM

Our hitch pro writes: "If you have a hitch on your vehicle, it is possible that a 4-flat wiring harness was installed at the same time as the hitch. The 4-flat wiring harness can be stowed in several places, try looking directly behind the hitch or in the storage compartments located in the rear cargo area. If you are unable to find a trailer wiring harness, please visit your local U-Haul center for a free towing inspection or have U-Hauls 4-flat quick connect wiring harness CQT118426 delivered directly to your home by purchasing at uhaul.com."

–Ronald 10/22/2014 10:12:56 AM

I recently purchased a 2013 ford escape that was already equipped with a u haul hitch with a harness that looks like this except it has three lights that light when the vehicle lights are on. I just purchased a light trailer equipped with the same type of harness. When I connect the lights go out on the harness and the trailer has no lights. If I connect the trailer to a different vehicle there are full functioning lights. Any ideas as to what is not working?

–Bart 3/24/2015 8:13:41 PM

Your trailer lighting issue is caused by an insufficient ground. Please visit your nearest U-Haul hitch location, the U-Haul hitch pro can quickly diagnose and repair your lighting issue.
