Quickly and easily install this custom harness to get a 7-way and a 4-way trailer connector on your vehicle. Connector plugs into OEM tow package wiring harness - no cutting or splicing required. Weathertight seal deters damage from water and debris.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. 578764
Heather A - 10/30/2018Great 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. 363108
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. 258277
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. 435165
Fit right and was exactly what I was looking for. Good service and prompt delivery. 54898
This product was designed for vehicles that had a previously installed 7-Way that needs replacing. It may work on your Expedition but may require additional fuses or relays to be installed in the fuse or power distribution blocks. In case the factory wiring plug is not there, check out part 37185 so you can manually splice in.

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. 328529
Laura E - 02/10/2017This 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 330310
Paul B - 01/06/2018Easy 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. 141074
Patrick L - 07/20/2015My car is a 2012 Grand Cherokee SRT8. Installation was easy. Although I do not have the factory tow package, the energized wiring harness was present with a round plug inserted. No need for dealer assistance! Both parts arrived timely and well packaged. am very pleased. 884023
Everything was great. Fast shipping. Easy install. Will be buying from you guys again!! Thanks 853295
Turns out I bought the wrong kit, no worries, ordered the right one, expect it in about a week or so. I'll let you know how it goes. The tow bar is heavy duty that I bought with the first wire kit. 840110
