  • Trailer Hitch Wiring
  • 4 Flat
  • Powered Converter
  • CURT

Quickly and easily install a 4-way trailer connector on your Ford Transit T250 with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.

  • Connects quickly and easily
    • Locate connection points behind tail lights

  • Maximum amperage:
    • Stop/turn lights: 3.0 amps per circuit
    • Tail lights: 6.0 amps per circuit
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your rear cargo area, behind the driver's-side and passenger's-side tail lights. You will have to remove the rear scuff panel to access these connection points. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.


Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your cargo area.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.


Powered Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.


Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.


Curt SMT Circuit Boards

Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.


Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

This item was placed inside box with hitch receiver. When I got it the package was crushed, and the little converter box was cracked. It works but I was disappointed.

E-trailer is the one stop shop for everything trailer!!! The hitch works perfectly on our church van

The trailer hitch is working just great, It was easy to install if I remember right we did have to do some drilling but no big deal.

This is an easy to install kit, and the install video made it even simpler. I chose to mount my wiring on the left doorpost, where it can easily be pulled out through the rear door weatherstripping when needed. I was able to keep all wiring inside the van compartment and frame rails. Two hopefully helpful comments:
* In order to mount to the door rail, it is necessary to splice in a couple of feet of wire to the green wire between the two light buckets. By cutting this wire, I was able to snake it through the frame tubing under floor behind the rear door latch. I did not have any wiring outside the vehicle.
* There is a wiring lug available on the side of the driver's seat, adjacent to the battery compartment, which may be a more convenient lug to attach the hot wire to. The video shows running the wire all the way to the engine compartment.
Best of luck.



by:
2020 Ford Transit T350

Liked the kit but found a better way to install without cutting grommets. Mounted below drivers side tail light. See pics. Power wire was run all the way to the fuse box under hood instead of battery under drivers seat. This kept all wiring outside keeping all grommet seals intact, and saving time on removal of interior panels which are difficult with 15 passenger seating still installed.



by:

The only issue I had to deal with was mounting the harness box. I eventually gave up and used a wire tie to mount to existing hole. 44° may have been the issue with the double stick tape?
Other than my vehicle's panels and battery under driver's seat, the install went well.

I actually have not used the hitch yet. This is on a 350 Transit, I used once to haul my Indian. After installing one on my Cherokee, for the money, I had to put one on this too.



by:

This wire kit came complete with everything needed to do a clean install. We used the eTrailer vehicle specific installation video, which made it easy to install. We highly recommend this kit to complete your towing setup.

Could be as simple as plug into a factory pre-wired harness on my 2020 transist. Way too much work to get wires completely hidden



by:

easy to install great price

Again the service and products are awes ome!



by:

Our previously installed harness quit working. Something got fried inside the converter. The part we ordered from etrailer was literally a snap to install and works exactly as it should. So my trailer lights are back in business! The price was right, shipping time was acceptable and it took me about an hour to remove the old harness and install the new.

Regarding installation on a Ford Transit: I've seen several comments about the difficulty of making connection to the battery, which is under the drivers seat. Our van has a remote positive terminal in the engine bay to make jump starting easier. Our original harness was wired to this terminal, so I just kept the wiring in place.

Very well assembled kit. I used the e trailer install video and followed it step by step. Although very informative the video and printed directions did not address Transit 150s with finished interiors. Unable to route my power cord along the wall I zip tied it underneath then ran the line to a 1/4" hole I drilled under the seat between the base and wheelwell upper edge. Completely hidden and a straight route to the battery under the seat. Total time about 1 1/2 hours.

Were glad to hear the install worked well for you. Youll want to make sure that you use a grommet or some silicone caulk to protect the wire where it passes through the vehicle firewall, the metal edge can abrade the wire over time and cause the copper conductor to short out on the metal.

2015 Ford Transit Connect

I bought this thing so that I could put a trailer hitch on my 2015 Ford transit 150 work vehicle. Because the transit is a real POS it wasn’t easy. But the instructions were comprehensive and the installation went as well as could be expected. The product worked flawlessly and has worked for over a year now. From a trailer wiring standpoint this is not a bad deal. Shipping was as promised, I had no reason to talk to the people about a customer service issue. It got four stars instead of five because I had to install it on the stupid transit van. I hit my head twice under the truck and I carry a grudge. I know this isn’t etrailers fault but somebody has to pay.



by:

Really like this item. The kit is complete with everything needed to do an average (read: mediocre) installation based on the etrailer videos.
In order to do a truly exceptional, professional installation there needs to be some changes to the wiring a bit.

I mounted the control box on the 'inside' of the D pillar right behind and above the rubber grommet that houses the OEM lead for the left rear tail light. The location shown in the videos is unacceptable. Since my mounting location inside the pillar is higher, that caused the wiring to be short for the right side which required another 18 inches of wire spliced in. Also, since the D Pillar on the Transit is Boron hardened, it's almost impossible to drill through which required locating the ground to another location below which could be drilled with the self tapping screw.

The real fun begins when its time to run the 12 volt power lead to the battery.
The video shows the basics on the proximity to run the wires and where to mount the Ring connector to the lug next to the fuse box under the hood.
What the video didn't show was the huge PIA it is to route the wire keeping it away from heat sources and anything that might cause abrasive forces to the wire over time. The video showed the van up on a lift where the installer could have 'easy' access to all of those little nooks and crannies, and probably with some help from a second person.
Try doing all of that while the vehicle is not on a lift, where you have to raise the vehicle for access so you can get underneath to run this one wire.
I used a good amount of plastic loom where needed, but was able to eventually able to get the wire to the 12 volt source per the instructions.

Please don't take this as a complaint. I knew what I was getting into before ordering this kit.
It's just that the videos are a bit misleading in terms of the time requirements. It takes a whole lot more time than they say, and it's not really 'easy' per se... it is more of a challenge.

The hardest part for me was to fight the urge to forego my principles of maintaining excellence, for mediocrity just to avoid the hassles of doing the job the right way as opposed to taking the easy way out...

Regardless, I'm still giving this item 5 stars. It's truly a great kit for the money. Just do the job the right way from the beginning and you won't have issues later on.



by:

The product worked as expected. AAA for the instruction video. Easy to use website. Highly recommend

2021 Ford Transit T350

I was able to install it, but there were some serious hurdles. The cables were too short for the transit 350HD crew. I had to extend both the black wire that goes to the battery as well as the green one that goes to the other light. The most time I spent on identifying the problem with one wire that was loose in the socket.
I was able to resolve the problems and it works now as desired.

It is possible that depending on how the wires are routed that additional wiring may be needed. I recommend taking a look at the video install that we did on a 2106 Ford Transit T350. And the FAQ on routing the power wire under the vehicle.



by:

Had Uhaul do it originally and everything they did failed including brake controller.
Replaced all their junk and every thing I did still works perfectly.
Simple install process and strongly recommend if your trailer has old style bulbs.
If you don't use this device with bulbs you will fry you BCM. LEDs seem to work. Ford is ignorant to it so if your van lights stop working, tell them replace the BCM, no need for their diagnosis.



by:

The kit comes with everything you will need to wire for a trailer plug. The only thing I needed to modify was the green wire for the RH turn/brake signal. It is a little short. The connectors were of good quality and it is a simple install. You will need to remove the driver's seat to access the battery for the 12V power wire unless you are making your connection under the hood

  • Recommended Trailer Wiring Harness for 2019 Ford Transit T250
    For your 2019 Ford Transit T250 I recommend the Curt T-Connector Vehicle Wiring Harness # C56327, which will plug right into existing ports behind the tail lights and features an extremely reliable converter box that has shown itself to be superior to those from other manufacturers. After making those connection behind the tail lights you will also need to run the hot lead up to the Transit's battery for power.

There was a bill passed that protects consumers from any type of cancellation of warranty when adding aftermarket components such as wiring harnesses.

    Hey Mike thanks for your question. The T-Connectors, like the Curt # C56327 you mentioned require a line to be run to the battery to power the converter. The converter basically serves to protect the wiring on your vehicle. It is circuit-protected, and battery powered which allows for virtually zero draw on the vehicles tail light circuits. We get this question quite a bit regarding the powered converters and the answer is universally, yes, running a wire to the battery is required, even...

    For your 2020 Ford Transit 250, I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56327 for your trailer wiring. The 6-pin connector you referenced is not the correct harness for your trailer wiring.

This will also draw power directly from the vehicle battery to protect your vehicle electronics.

  • Does Install of Trailer Wiring on Vehicle Drain Battery
    It would be incredibly out-of-the-ordinary for a trailer wiring harness like the Curt # C56327 you installed to cause a dead battery on a vehicle. Most likely what happened is that when you installed it last night you had the doors/hatch open which was running the interior lights for an extended period of time which then drained the battery. And it wasn't until this morning that you tried to start the vehicle this morning that you noticed the dead battery.

    The only descriptor that changes the trailer wiring harness needed is whether your 2020 Ford Transit T350 is a SRW or DRW model. If your 2020 Ford Transit T350 has single rear wheels as opposed to duals, the # 118643 Tekonsha trailer wiring harness would work perfectly for you. If you have a dual rear wheel model, use # 118722, either of which would provide a 4-pole trailer connector to provide basic lighting functions to the trailer.

    Is the issue possibly on the trailer's wiring? Use a circuit tester like the # PTW2993 to test the pins of the 4-way for voltage and see if the trailer wiring or the vehicle wiring is the problem. Sometimes it's just a weak ground on the trailer wiring which you can improve by checking the main ground wire connection from the 4-way to the trailer frame. Sometimes it's just that the connectors of the trailer wiring need to be unplugged and plugged back in.
