Perfect fit on my 2000 Ford Ranger! Shipped very fast and in perfect condition! I installed in my driveway in about an hour. Fit like a glove. It looks great! Will order again!




by:
2000 Ford Ranger

My new boat's trailer 4 flat plug would not fully insert into the factory 4 flat connnector on my Ford Ranger. I hadn't previously used the factory connector, so I think it was related to corrosion.
I researched after market trailer wiring options and purchased this one from etrailer.com. The order was prompted filled and shipped.
The harness is well constructed with heavy gauge wire and insulation and was guaranteed to fit my Ranger.
I installed the harness per instructions and it worked like a charm.
This was an excellent solution to my problem.


Comments
The harness is still performing flawlessly.

Just what was needed for my 2002 Focus Wagon. It's hard to find perfect fits for an older car.

I am totally pleased with the service that I received, the salesman Alex, is one of the most professional and helpful people that I have ever dealt with




by:
2003 Ford Explorer

Extremely easy to install. I also installed a 4 to 7 adaptor (30717) and a 7-way connector box (18159). All of this took 30 minutes to install and it looks and works great. I use etrailer for all of my cargo and trailer needs and recommend them to my family and friends.




by:
1995 Ford F-250 Super Duty

Product C55344 - says no splice but I had to cut trailer lead off to fish wire to bumper and drill a hole in the passenger tail light bay to install on
1995 Ford F250.
Instructions are not model specific.
T connectors worked as they should.
Thanks

This hitch was better than I expected. It was much heavier and well manufactured. The video on the website explaining installation was easy to understand and made installation easy. This hitch and light accessories were far superior to those sold at UHaul and auto part stores.

I fitted this while doing i was fitting my new class 3 hitch. Ford Explorer 2002 4 Door 4.0L XLT. Worked great.

  • Install Video for 4-Pole Wiring for 2001 Ford F-150
    Part # C55344 works for your 2001 Ford F-150. We do not currently have an install video for you to reference, but this is a straight forward install. You remove the driver side tail light, plug in the new harness, drop the rest of the wires down, run the green wiring to the passenger side tail light and make the connections there. I attached the instructions to help walk you through the process of getting the wiring installed.

  • What Hitch will Fit a 2003 Ford E-350 Cutaway Chassis
    The Curt hitch part # 14055 will fit the cutaway models of the 2003 Ford E-350 if the bolt holes on the frame of the van are 38-1/4 inches apart on center. I attached an install video for you to check out as well.

  • 4-Way Mounting Bracket Recommendation for Use with Curt Wiring Harness C55344
    For a 4-way bracket to use with the Curt wiring harness part # C55344 that you referenced the most popular option is the # 18144 which will drill to the bottom of the bumper on the vehicle and hold the 4-way. I attached a review video for this bracket for you to check out as well.

  • Trailer Wiring Harness for 1999 Ford Escort Wagon
    Because the 1999 Escort Wagon uses a separate bulb for the turn signals, and would need a taillight converter, the # C55344 would not be compatible with your Escort wagon. To combine the brake light and turn signal onto a single circuit like the lights on the trailer, you will need to use a hardwired tail light converter like the # 119178KIT. The wires on the input side of the converter would wire directly into the taillight circuits of your Escort wagon. The easiest way to access the...

  • Hitch Recommendation for a 2003 Ford Ranger with Body Lift
    Yes, the Draw Tite Hitch part # 75082 that you referenced will fit your 2003 Ford Ranger with a 3 inch body lift. This hitch attaches to the frame of the vehicle so the lift kit on your truck won't affect the install. I attached an install video for more info. If you plan on doing some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also includes a...

  • Troubleshooting Trailer Wiring Harness for Class C Motorhome on 1998 Ford E350 Van Cutaway Chassis
    I would first spend a few minutes trying to trace the wires feeding that 4-pole trailer connector you found. If the white ground wire had come loose from its connection with the RV frame or chassis, it would explain why you're not getting any voltage at the connector. If that fails, you'll need to simply hardwire in a new trailer connector like part # 18002. The green wire would tap into the right turn signal circuit, the yellow wire into the right turn circuit signal and the brown wire...

  • Adding Trailer Wiring or Troubleshooting Only Running Lights Working on a 1997 Ford F-150 Connector
    To add a 4-Way trailer connector to your 1997 Ford F-150 you can use # C55344. This harness plugs in line with the tail light wiring on the truck. It will provide left turn/brake lights, running lights, and right turn/brake lights. I have included a link to the installation instructions for you. If you are having trouble with a 7-Way trailer connector then it is possible that there is a blown fuse or relay that is causing the problems. Use the vehicle owners manual and/or the legend on...

    For your 1998 Ford F-150 I attached a link that has all of the hitches available that would fit the vehicle. For one that would work on your vehicle if it has a standard or stepside bed you would want the Curt Hitch part # C14355. I also attached an install video for the Curt hitch. If you plan on doing some towing you might be interested in etrailer ball mount kit # 989900.

  • Recommended Trailer Hitch Receiver and Other Parts to Tow a Trailer with a 2000 Ford F-150
    I've linked all of the available trailer hitch receivers that fit your 2000 Ford F-150. Of the selection I recommend the Curt # 13359. It's a complete bolt-on installation and fits both the standard and stepside trucks. It also allows the full-size 20 inch spare tire to remain in place. I've linked the install details for you. If you also need trailer wiring you can add a 4-way using # C56031 if you have a standard bed or # C55344 for a Flareside. These both plug in behind the tail...

  • Recommended Trailer Hitch And Trailer Towing Setup For A 2003 Ford E-250

This is a class IV trailer hitch that has a maximum towing capacity of 10,000-lbs, with a maximum tongue weight capacity of 1,000-lbs, and will work great with your 2003 E-250.

  • Trailer Running Lights Stopped Working when Connected to a 2003 Ford Ranger
    It might be easier to fix the running light malfunction on your 2003 Ford Ranger tow package wiring than you might think. If it is just a tow package fuse that is blown you can replace the fuse. But you will have to make sure that whatever blew the fuse in the first place is fixed first. Make sure the truck side and trailer side connectors are clean and free of corrosion inside where the wires attach and outside on the pins. Inspect the trailer wiring for any pinched or damaged wires and...

  • Hitch Recommendation for my 2002 Ford Explorer Sport
    For your 2002 Ford Explorer Sport you will use the Curt Trailer Hitch Receiver part # 13540. This was custom designed for use with the Explorer Sport or two door model. The Draw-Tite Max-Frame Trailer Hitch Receiver part # 75112 was designed for use with the Ford Explorer Sport Trac which was a slightly different model and will not fit your Ford Explorer Sport two door. If you'll be hauling a trailer use the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part...

  • Adding a 4- and 7-Way Trailer Connector to a 1999 Ford E-150 Van
    To add a 4- and 7-Way trailer connector to your 1999 Ford Van you will first install a 4-Way such as # 118344. Then, with the 4-Way installed you can install # ETBC7 to add a 7-Way and retain the 4-Way. I have included some links that show and explain the ETBC7 installation for you. These links also cover the installation of a brake controller. For a brake controller I recommend the P2 # 90885 because it is easy to set up and use and it is reliable.

  • Will Trailer Wiring Harness 20028 Fit a 1998 Ford F-150 without Factory Trailer Connector
    To solve the problem of the dirty connections you can clean them, then use dielectric grease at the connections, # 11755, and then seal everything up using liquid electrical tape, # SWC50122. Another option is to replace the 4-Way you are using with either # C56031 for a non-stepside bed or # C55344 for a stepside bed. These connectors actually plug in line with the tail light wiring so you will not have to use quick splice connectors.

  • Custom Fit Trailer Hitch, Wiring, And Ball Mount For A 1999 Lincoln Navigator
    For your 1999 Lincoln Navigator, I recommend taking a look at the: -Curt Trailer Hitch Receiver # C13049. This trailer hitch has a maximum towing capacity of 6,000lbs, and a maximum tongue weight capacity of 600lbs, however I recommend taking a look at your owner's manual for your vehicle's maximum towing capacities, and ensure you're utilizing the lowest number between the hitch and vehicle. Additionally, for a complete towing setup you're going to need wiring # C55344, and a ball...

  • Curt Towing Parts needed for 2002 Ford Ranger and How Loud is Magaflow Exhaust For It
    We have all of the Curt towing components you mentioned individually but we do not have them as an entire kit. So we have the Curt hitch # 13138, the wiring # C55344, the ball mount # C45010, the hitch ball # C40002, and the pin and clip # C21500. The Magnaflow Catback # MF15679 is going to be noticeably louder than what you have but not to the point it would be annoying. If you fast forward to the 2:20 mark of the install video I attached for this you can hear the difference as well.

  • Is There A Class 4 Trailer Hitch Available For 2002 Mercury Mountaineer
    We do not offer a Class lV hitch for your 2002 Mercury Mountaineer, but we do have a couple of hitches that would possibly work for you. The first hitch I recommend is the Draw-Tite Max-Frame Trailer Hitch Receiver, part # 75132. The trailer hitch has a towing capacity of 5000 lbs, unless weight distribution is used. Then the maximum towing capacity jumps to 8000 lbs. When you are towing anything that weighs more than 50 percent of the towing vehicle, weight distribution is recommended....

  • What Makes the etrailer Trailer Hitch Different Than Other Hitches for a 2003 Ford F-150
    The etrailer Trailer Hitch Receiver # e92KR differs from the other fits for your 2003 Ford F-150 in that it has a matte black finish. This not only looks more rugged but is more durable than the classic glossy black finish we see with the other hitches. I really like this finish and recommend it as often as I can. If you don't already have trailer wiring on your truck then I recommend the Curt T-Connector # C55344 if you have a Flareside or SuperCrew or the T-Connector # C56031 if you...

  • Brake Controller Installation-2003 Ford Expedition
    I don't have a vehicle specific wiring diagram for you, but I'd be happy to walk you through the process. The actual installation will depend on whether or not your Expedition is equipped with a trailer connector and if so, whether it's factory or aftermarket. There are a few different possible scenarios. 1) Your vehicle has the factory 7-way trailer connector on the back bumper. If this is the case, you'll have a plug and play installation. You'll need the # 3035-P brake controller...
