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.

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

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

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.

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.

Not a bad product, but power cable was way too short and same as the left side signal light assembly wiring was way too short, had a slice both in

I have a 2017 Transit 350HD w/long wheel base. There were a few problems with this item. First of all, I wouldn't recommend following the instructions provided. It is much easier to run the wires down and under the vehicle. Just look up a video. I had to take it all apart after I put everything back together because there is no way to get the 4 pin plug down and out without drilling a hole so I routed it down and outside from the light instead. Secondly, the plug and play adapters don't fit the plugs correctly. They have these little wings on the plugs that slide into the molded grooves before it clips in. They don't align with the factory plug. I had to use a knife to shave it away to get it to go in and click. Very frustrating. Third, the black wire they supply to connect to the positive terminal is about 4 or 5 feet short on my extended wheelbase model. Had to find some wire to splice and extend. Lastly, it shows a 10 amp fuse in the picture in the product description but one was not included. It is a cheap item but I didn't have one laying around so couldn't finish the job until I get one. All in all, should be good but it misses on all of those points.

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