2004 Ford F-250 Super Duty

This is the wrong receptical for my f250 super duty Ford pick up lariate truck. I waited 20 minutes on the phone and no one picked up.Or send me a return receipt

I will have our Customer Service team reach out to you. I do show that this harness is a fit for a 2004 Ford 250 with the factory seven way.
-- Etrailer Expert Jenny N - 04/28/2022


The one I received has round plug. Need one for square. This is a 03 f250

If you have a factory 7 way then this product should work for you and the plug in should be under the vehicle on the driver side. If you have a factory 4 way you will need something like item # HM40165
Hopkins Plug-In Simple Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector
. If you do not have any factory wiring you will need something like item # 18252

2010 Toyota 4Runner

Easy peasy....unplug the old...plug in the new!

On the 2010 Trail Edition 4Runners...the engineers mounted the plug up and underneath. I understand why (so it didn't get torn off) but what a huge PITA plugging it in and out.,plus its not a natural position hanging down that way.

I used one of the existing bolts holding the plastic bumper cover on. I just enlarged the hole in the socket bracket to 3/8"s. The other hole in the socket bracket I used a #10 self tapper (the mounting screws included are insufficient IMO)

I used dielectric grease at the fitting, pushed them together, taped it all up, and that was it. I screwed the plug into the socket holder and that was it...nice, strong mount.

I will say for you that use your spare in the factory position to get the longer length tail. I got the 12", but if I did use the spare it would be difficult. I realize it hangs down, but I tow much more than I rock crawl...I'll just have to be more cautious.

Thanks for the follow up Rachael...Im still very happy with it. I do lots of off- roading, and its holding up just fine!.Have a great summer!

2001 Ford F-250 and F-350 Super Duty

I thought this would plug right into my factory harness. My harness has a square plug. The one you sent is round. It does not fit. I could have got this at the local parts store. Don’t need it.

It looks like your 2001 Ford F-250 super duty has a towing package with a square plug. You will need part # C55243

2021 Ford F-150

I entered the year of my truck for tow hitch and harness for trailer. Hitch fit perfectly but harness isn’t the correct harness

I will have our customer service team reach out to you. This harness is intended to replace the factory seven way on your 2021 Ford 150 to give you a 7 and 4 way connector. If you do not have any wiring installed on the truck then you would part # C75WR
Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector
to give you a 4 flat to start. Part C75WR is intended for trucks without LED lights and is not intended for models with back up sensors.
-- Etrailer Expert Jenny N - 02/15/2022


Needed to pull a car dolly. This worked fine for dolly and towed vehicle lights. Easy install.

still good

Ford F-150

I am not sure how it happened but my OEM connecter came up missing from my F-150. OK no big deal, the truck is paid for and I am a bit busy and a little lazy so while I was have the oil changed at my dealership, I went to the parts counter to get another one.......WHAT? About 400.00, are you serious? Then I stumbled across this one, and it cost about what the sales tax was from FORD. It was so easy to install I was almost ashamed it took me a month to order it. There are tons of other things on etrailer that I will be buying in the near future. Thanks, guys. This was more than I bargained for.


Although it worked well it was NOT a plug and play as advertised. However I do have an extensive automotive electronics education I was able to make it all work as needed

2014 Jeep Grand Cherokee

Fit great with the Draw Tite hitch, 2014 Grand Cherokee. Whole process of install about 20 minutes, hitch and wiring. Tarp and hand tools. No jack or impact required.


Never installed it. This was for a truck that has wiring readily available at the bumper. I have a F150 Heritage that the factory plug was much further away. I did reach out to etrailer, but was asked to take pictures of the plug and location on the truck. By that time, spare tire was already back on and truck was in use. It was too much of a pain in the arse to take the pics to supply to find the right one. Though I am sure this will work fine if it were the right part, 2 stars are for the web site. VIN matching would be nice. The choices for F150's were a pain in the butt.


2004 f350 The bracket is no where even close to the factory bracket. It is not tall enough and would require and drilling into the bumper, 3/8" carbon steel. I went and bought ford bracket, it was even less than this kit.

2011 Chevrolet Silverado

Highly recommended - bought this for my son's 2011 Chevy Silverado 1500 and installed myself - it looks factory installed and works perfectly. Whenever I'm shopping for trailer items, I always look first at eTrailer. Their product video reviews are helpful as well.

2002 Ford F-250 Super Duty

This purchase was to fix a damaged factory trailer wiring receptacle. The application it was going on was an 02 Ford F-250 truck. The unit came with the 7 wire connection along with a 4 flat connection along with a mounting bracket. The factory receptacle had a connection that went directly to this new harness and was a dead on fit. Only problem is now I have 2 of the 4 flat connnectors. The new harness came with one and the factory harness has one as well. I really only needed the 7 round connector. The metal bracket that came with the package was flimsy metal and the factory bracket was much better. I just had to drill new hole for the new socket to fit the old bracket. Wiring was zip tied up after connections were made and coiled up all the excess cable. Socket was texted with trailer plug and now lights work again. Yippee

Still working great

2018 Chevrolet Silverado 1500

Just plug and play. Easiest install eve r.

2009 Toyota Tacoma

This did not fit on my 2009 Toyota Tacoma. Upon contacting etrailer, they checked with one of their contacts who informed them that my truck must have been modified at some point. I was at the dealership when this truck was backed off the trailer with 2 miles on it and was still wrapped. The tow package was already installed when it came of the transport. Etrailer offered for me to send the product back or if I wanted to modify it myself. Due to the price, I decided to modify. I matched the wires color for color and when plugged in, the lights were all out of whack. I took off the connector, threw it in the trash and headed to Toyota for a factory replacement which solved my issue. I would do business with etrailer again, just not for this product.

Thanks for your review and your business, Chris. On some 2009-2012 Toyota Tacomas with factory 7-ways, the connector will not come apart for this product to plug into, so the connector ends have to be cut off and hardwired together.
-- Etrailer Expert Laura E - 02/10/2017


Great product, I much prefer having access to a 4 and 7 pin plug over carrying around an adapter. The adapter is one more thing that can be lost and it adds an unnecessary connection which means an unnecessary extra potential point of failure.


Fit perfectly. Well constructed and designed. Came with a mounting bracket for the bumper. You might need some zip ties to complete the installation.


Does not fit 2009 Tacoma as advertised. Returning part.

You mentioned that it was not fitting on your 2009 Tacoma and I wanted to ask you a few questions. Can you explain in more detail how it did not fit? Did your truck come with the factory tow package?

2014 Jeep Grand Cherokee

This is my second hitch and wiring from etrailer. Both have been simple installs and the videos that etrailer has are so helpful!!!


Very happy with product thanks a lot! As described it was plug nd play took me literally about 15 20 min to find where I wanted to mount it and ran the wires. Talking my co-worker to order from you guys he needs one for his kia


There is nothing wrong with this item, it is simply not the item I need.

2015 Chevrolet Silverado 3500
