56327 Vehicle-Side Custom 4-Pin Trailer Wiring Harness for Select Ford Transit

I added a tow hitch system to my 2017 Ford Transit 350. (surprised it didn't come with one from the factory to be honest) I got my quote from Uhaul and the hitch part was reasonably priced ($124 plus $15 labor). However the part of the bid for running the electrical was about ($283) for their end (kit and labor) . I felt this was a gouge so I went looking for the kit to do it myself. I hadn't really ever done car electrical projects before except change light bulbs. I've never swapped a radio, hooked up and speakers, tinkered with other electrical systems, etc - to give you an idea of my limited experience working on cars. However it's as simple as securing an inverter box behind a panel close to your tail light, running a wire through a rubber grommet into both your tail lights, clicking in the adapters to the built in wire harnesses, and running an included wire for 12v power to the battery. The only part of installing the wiring that will be different vehicle to vehicle is the location of the battery. Obviously in the transit van your battery is under the driver's chair, so the natural choice is to run the wire inside. My van is also carpeted so I tucked the power wire along the edges all the way up to the front of the van, being careful not to poke any holes in the wire sheathing. The installation overall is not difficult, just takes time to run that wire to the battery and make it hidden/pretty. I had uhaul test the connection with their plug a week later when my appointment was set for installing the hitch. Everything checked out and transmits beautifully. First try, success. Surprisingly easy, and cheap. Saved me 230 bucks for doing that part myself. In total for the tow hitch system - instead of spending $428, I spent $195 due to doing this part myself. Great product, works, not too tough to install yourself.

Works like a champ

CURT is a trusted brand. They were easy to install, the plug in connections work well. Good value for the money.

Great trailer harness, plugs directly into factory lights. Installation is easy, but the instructions are for a cargo van, not a passenger. It is much easier to route into the engine compartment instead of the battery under the driver seat. It would be nice if the power wire was a foot longer for routing it this way, there is not one spare inch of wire.

The positive (20 foot) black wire in the kit that I was required to run underneath the Van from the front Battery connection of my Transit Extended Long van to the back left taillight was a little on the short side, however I was just able to make and complete the connection. However, the black "positive" wire could have been about a foot longer on my 2018 Ford Transit 250 (Extended Long) Van. You will also need a variety of hand tools: Wire cutter, Wire stripper, Wire crimper, Drill, and Drill Bit. In addition, I recommend you purchase (teflon heat shrink "ring connectors"), and double sided teflon connectors to replace the ones that came in the kit. Available at (OReilly's) This will waterproof your 12 Volt electrical connections. I used a Bic lighter to heat these heat shrink connections. If your prepared for the installation it will proceed much easier and faster.

Works as you would expect, photos are dark, it's quite simple to install

Used on a 2022 Ford Transit 350 HD DRW Extended. Kit was good, had to add wire (used 18awg) for connection from drivers to passenger side, and add wire (12awg) for the power connection from back to front. Cut off a tab on the connectors in the tail lights so they would connect as the OEM tab slots were slightly off. Overall good kit for this vehicle.

They didn't send a wire long enough to reach the battery to the front! Wasting an hour with drive time and extra work to save a dollar in copper is a telling of how these companies cut corners any chance they can!

Works good but unfortunately did not get a chance to try out, as my vehicle burned down. This harness is NOT cause.

No se adapta a cualquier carro solo unos cuantos y no traen todas sus piezas
