Reese Multi-Plug Wiring Harness for Factory Tow Package - 7-Way and 4-Way Flat Trailer Connectors

wasn't exactly what i needed, Not E trailers fault or manufacturers fault. It was my fault. I made it work right. It was exactly as i ordered and was packaged nicely arrived when i expected. hooked it up drilled some holes and soldered some wires. Made for a good afternoon with my dog and truck! And by the way if you can figure how to wire this and drill some holes this is much better than the ford oem unit ! and im a ford guy. 569495

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

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. 328529

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.

I purchased and installed both the Hidden Hitch Class III Trailer Hitch Receiver as well as the Tow-Ready 7-Way 4 Pole Trailer Connector, part number 20119 on my 2012 Jeep Grand Cherokee. Both were very easy to order and a snap to install. Since I was working alone, I used the recommendation of using a hydraulic jack to raise the hitch receiver, and that worked like a charm. The instructions were very easy to follow and the additional videos of the installation were a tremendous help. One problem I have encountered which I must mention, has to do with the Jeep Factory 7-pin Wiring harness. My Jeep originally did not come with a factory hitch, but this model does come with the 7-pin harness with cover. When I plugged in the new Multi-Tow connector, only the running lights worked. Both Turn signals and Brake lights do not work. Apparently, I needed to add a 10 AMP mini fuse which I did, but still no lights. From researching Jeep Forums, I discovered I must now also go to my Jeep dealer to "Re-flash" the PCM (BCM??) with some sort of "tow package" specialized program so that I can have all functions of the trailer connector. After speaking with the Dealer, they can do this "No-Problem" for me, but it will take a 1 hour appointment and will cost about $60. This would be good additional information for your next customer when they purchase the "Tow Ready" custom fit trailer connector. If/When I get this completed, I will follow up with an update. 186812

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. 363108

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 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

Still working great

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. 141074

Great quality products, and very easy and simple to install. I was able to install it by myself, and it only took me about an hour. 10/10 would recommend. 612431

I had my local automotive repair shop install the hitch. All went well. 609913

Plug right in easy install two thumbs up 594503

Great help. Fast Fast Fast... 588664

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

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

It was exactly what I needed to get my Jeep ready for towing my camper. The site was full of so much info to help figure out installation on most of the stuff I needed. Still working great after a year. 424683

I enjoy ordering from eTrailer, very simple and helpful. I was not satisfied with this product, I was told that this would fit my F250 Super Duty which it does, I called and asked because the picture did not look right, and was assured that it would work. Once I received it, It does not have the correct end connection. I needed the the end connection that looks like part # C55243. I paid for 2 day shipping to receive the part before my truck went to get painted and now the part does not work. I will be ordering part # C55243 when I get my truck back I think the product is a great product, Reese is a name I can trust, just not very good on telling me what kind of connectors were on it. 420097

The item was shipped on time. It was easy to install. It looks great and fits perfectly 407572

Perfect length and fit to add a trailer plug to my existing wire harness. My 2003 Tahoe didn't come with the tow package but there is a connector near the spare tire for plugging in the tow harness, thanks for making this so easy. I used a hole saw and recessed plug into my bumper like the factory would have done. 398339

Easily installed onto my 2014 Jeep Grand Cherokee, wiring was already provided and just had to plug it in. Still haven't checked the lights as I know I will most likely have to go to the dealer and have them activated. Only issue was it only came with 4 screws and nuts, had to purchase two additional to fasten to trailer hitch. 392154

As expected, no difficulty in installation. Thanks! 389313

Once I figured out how to disconnect the original trailer hook-up, the rest was a breeze. Finding a suitable location was a bit of a challenge on a Lincoln Navigator, but it all worked out. This was way easier than having to splice wires together and I really couldn't make any mistakes. 380761

Easy to install and does what it says. Plug fit in existing wiring harness, there was a cap on it that took a few minutes to get out but after that it plugged right in. In my case I had to go to the dealer to get the lights turned on in the computer because it didn't already have the towing package. Cost about 60 bucks, I think they called it an accessory install. 360448

Etrailer has literally the best customer service I have ever had. I even got a call that my order was processed and in route - from a real live person. They have always had everything I needed and great guides to make sure you are not ordering the wrong item. I will definitely be back! Perfect job guys and gals! 359133

Got here in 3 days. Very surprised. A fair price. 340261

E trailer gets 5 stars, fast shipping and product was exactly as advertised. The product itself I'm giving 4...because there's no half and I made minor mods to get it to work on a 05 Superduty. Its about 75% "plug n play" for this vehicle. #1. The included bracket didn't clear bumper and trim. Reused the OEM bracket which is a good bit heavier material and provides the adequate drop. You'll need to drill holes in the OEM bracket as the spacing is different. #2. The vehicle connector doesn't lock to Ford OEM harness. The electrical connection is fine and its snug but the prongs from the factory plug are far too short. Considering this is a multi fit item its not a huge deal, especially considering the savings over an OEM part. Some e-tape and a zip tie fixed that. Also used some dielectric grease on the contacts. All in all, it works as advertised, would recommend and would buy again. 336890
