Quickly and easily install a 4-way and 7-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into OEM tow package wiring harness - no cutting or splicing required.
This custom-fit T-connector plugs into your vehicle's factory tow package wiring harness, which is located at the rear of your vehicle, slightly toward the driver's side.
Once installation is complete, the connectors will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket is included to keep the connectors secure.
It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 7-pole and 4-pole connectors - to help prevent corrosion.
Note: Refer to the diagram above to determine if this harness will fit your application. The plugs on your vehicle must have 5 terminals on one side and 2 on the other. If your vehicle has 3 terminals on one side and 4 on the other, you will need wiring harness HM43385 instead.

Today, were going to review part number HM11143395. This is the Hopkins 7-Way RV and 4-Way Flat, Multi-Tow Wiring Harness for the Toyota Tundra. This part is designed to fit the 2007 to 2014 Toyota Tundra.With the factory 7-way, it is intended to be a factory replacement for your vehicle if it come equipped with the 7-way. Basically, it comes with all the parts shown here. The mounting bracket comes with the hardware to mount the bracket to your vehicle and to mount this connector to the bracket. It comes with some dielectric grease to put onto your connections to help prevent corrosion, and it comes with some detailed instructions to tell you how to install it.Basically, what you would do, this gives you a 7-way and a 4-way on your vehicle.
The way to install this is I would take your mounting bracket first and run it through on your cable, through there. Your mounting bracket has the four holes you can see that will line up to the four holes on the 7-way. Just line those up using the hardware and attach that, and then the other package of hardware is to mount this to the rear of your vehicle.The way you connect this is you just go down to the neck of your vehicle and disconnect behind the 7-way thats on your vehicle now, and you have these two plugs. One is a 5-pin plug. The others a 2-pin plug.
You would just match these connectors up to the ones underneath the vehicle behind the 7-way that you have now, plug them right in, then youd be all ready to go.That should do it for the review on part number HM11143395. The Hopkins 7-Way RV and 4-Way Flat, Multi-Tow Wiring Harness for the Toyota Tundra. .
Average Customer Rating: 4.6 out of 5 stars (112 Customer Reviews)Quickly and easily install a 4-way and 7-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into OEM tow package wiring harness - no cutting or splicing required.
I received my Hopkins wiring harness and day before the estimated delivery date. The kit itself was very easy to install. I did need to slightly modify the mounting bracket to match up the factory mount on my 2008 Tundra. Installation took all of 20 minutes. That's from removal of the old to the install of the new (including securing the wires from rubbing on the frame with a couple ties). Very good replacement piece. Thanks etrailer.com 80497

My truck: 2007 Tundra, double cab, SR5, build date 8/07 with factory tow package and wiring. The OEM trailer cord has two plugs which hook to my truck with a 2 prong and 5 prong connectors. The Hopkins HM11143395 which has this configuration is listed for a 2008 Tundra. A Hopkins 43385 is listed for the 2003 to 2007 Tundra. This cord has a 3 prong and a 4 prong arrangement. I think Toyota did a running changeover on the OEM trailer cord plug and hence that is why my truck requires the HM11143395. So buyer be aware. Check your connector plugs before ordering. HM11143395's bracket needed to be altered to mount to my truck. Everything is installed and checked with a meter but have not hooked it up to a trailer yet. Do not foresee any problems. 43232
I searched online for the correct trailer harness and couldn't find it for my 2007 Toyota Sequoia SR5. Even your website did not have anything listed for my vehicle. But I traced my short to the factory trailer harness (tail lights stop working, all other lights worked). Thanks to your detailed description, pictures and video, I thought I would give a try. All the other ones I found online did not look like my wiring connectors, yours look exactly the same as mine. Like you guys stated Toyota had a design change in 2007 for the Tundra, and changed it on my Sequoia also. Now all my trailer lights work perfectly. The only thing I had to do was make the drill holes bigger on the mounting bracket to align and fit perfectly with my factory location and bolts, not a big deal at all. Took about five minutes. Hopefully this will help anyone looking for a lower affordable price, for a factory replacement trailer harness for their Toyota Sequoia. I've attached a picture of my factory trailer harness connector. 201114

Product was easy to install. I actually installed it through the bumper so that I could not crush it AGAIN. With minor fabricating I had the old one out and the new one in within 25 minutes. Couldn't have been easier. Super fast delivery too! 116519

As other reviewers mentioned, the gauge of the mounting bracket steel is rather flimsy when compared to the original equipment. I reused the bracket that attaches to the vehicle frame by drilling holes into the Hopkins bracket and securing the two together. The product was simple to install and the electric grease came in handy. The shipping was quick as well. I would recommend this product. 138793
Enjoyed being able to review the installation in advance on the website , good stuff ! When the item arrived , it was a very simple install with the desired results . AND , the product saved me about $40 over similar advertised products . 138541

Electrical connector had all the parts and installed OK albeit with some modification as noted below. Getting the old connector off the 2008 Toyota Tundra pickup was the usual difficulty in figuring out how the electrical connectors disengaged and then getting the electrical connector mount off the pickup in one piece. I think the whole installation took 45 minutes which would have been a lot less the 2nd time around. The only issues I had with the product was that my Tundra had a vertical mounting plate so I had to bend the horizontal mounting plate from horizontal to vertical - a little work with a vice grip and a vice. Also the mounting holes were not the correct separation so I had to drill a new in the mounting plate in the picture. 299807
Fits my 2007 Tundra SR5 perfectly. I did not buy this as a replacement but instead an addition. My tundra was purchased without the tow kit; however, the factory left harness in and all I had to do was plug this in (check to see if yours is already there). Saved me a bunch of money as Toyota wanted over 200$ for this part... Not to mention the "labor cost." I mounted it differently because of the Hitch I bought. I used this: http://www.etrailer.com/Accessories-and-Parts/Tow-Ready/18136.html 116629
Harness: I like the dual type connection (I'm not a trailer guy) that apparently is the most common used. Hardware was zinc and because of potential rusting, I replaced it with weather protection hardware. The connections fit perfect, did not need to modify. Only modification was to the bracket; drilled holes so would fit horizontal to existing bracket rather than vertical. Hitch ball and mount: Fits great and works great. Good quality. For theft protection I purchased the receiver padlock rather than the coter pin style. Great quality and feels very sturdy. Glad I found your company, thanks bunches. Already told friends about your quality. 17868
This product was easy to install with minor changes to my truck. That said, the great part of this was dealing with e-trailer. I was on the verge of ordering the wrong product, and there was a page warning me I was ordering the wrong piece for my truck. After looking more closely, I would have been in big trouble and ruined a spring break trip. Thank you e-trailer, great experience! 73451
I'm not much on reviews. But after calling Toyota for this plug and getting a price that was crazy for a 18 inch pig tail. Then waiting for my normal mechanic for a month to screw around . He bought the wrong one after looking at it and having all the info in hand. So I finally told him ill take care of it . So in about 15 mins of me crawling under and double checking and comparing to the pic u provide on line . Very very pleased and I've been telling all my friends . U have followed up on every detail. Ill be back . Thank u . 75727

My 2007 Tundra factory 7 way harness was shorted out by a faulty trailer plug that melted my harness with the short. The Hopkins replacement worked perfectly. It did require drilling of 2 holes in the original mounting bracket to allow for the new mounting bracket to be attached but that was easy and fast. The 5 and 2 connections were factory exact and plugged right into the existing harness. I liked the vehicle specific videos that Etrailer produced for this part. Works perfectly. Thank you, Jim 274825

Very happy with my order from etrailer. You had my order in stock and it was sent right away. Even when I needed another part I was easily able to call your customer service department and they took care of me right away and were very nice! Your customer service department was the easiest department I've talked to. Thank you for allowing me to be a customer and taking care of what I needed. I will keep your company in mind when needing something again. :) 135969

Product received earlier than expected. Meets my expectations. Have not installed it yet as I just received it today but it is exactly what I was looking for. Dealer wanted to charge me $100 for the same piece, I am very glad I was able to find this which has more than what I asked for and was way cheaper. In the future, if I am in need of any trailer or towing accessories I will be sure to come back to this website. Thank you very much for your service. 63728
by: Patrick O.06/22/2011
Product exactly replaces the OEM unit at a fraction of the cost. I should have bought two in case I drag my back end and break it again! It's not that the quality is such that they break, but water bars and off roading can be hard on hitch components. The wire quick connectors clipped exactly into place. The mounting bracket needed some minor modifications, but nothing that you can't manage if you were installing this thing int he first place. 17642
by: Rick Hugi11/25/2014
Great product and much more affordable than OEM. Removing the left license plate light makes for a great alternative spot for your trailer connection. The chance of hitting it on a big rock again is gone. Lots of room behind for the wire bundle. 162406
This was really easy to install and all my trailer lights are working again! My factory connector gave out and all the female parts pulled out and left me with no trailer lights. Now I'm ready to go and tow again without the worry of getting pulled over and getting a possible ticket. Etrailer sent me an e-mail throughout the whole shipping process and wanted to make sure I was happy with my purchase. What an awesome experience! 220907
by: Peter G11/28/2016
The tow cable fit perfectly on my 2008 Tundra. I did have to make some modifications to the mounting plate since it was not the same as the original one on the truck, but this only took a few minutes with a cut off saw and a drill to make it fit the existing mount. After installing I tested the signals and they were all working correctly. Saved me hundreds! The dealer wanted $300 to replace the harness... 320058
by: Hal R.05/26/2011
Product works great. $300 less than what the local Toyota dealer wanted for the same thing. If I ever need an item(s) again I will check with etrailer first. The price for this item was less than the local automotive parts stores had for similar items that fit ford, chevy etc. Even with snail mail the package was here in the northeast in five days. Yes, I recommend etrailer.com to anyone. 15493
by: Paul C03/18/2016
No problem installing and the connectors hooked right up to my truck and it works perfectly!!!!! Thank you etrailer for an awesome product and an unbelievable price! 240969
by: Todd M.03/31/2016
Ordered this with economy shipping and I got it super fast! I had to modify the supplied bracket to fit my 2007 Tundra, but once mounted it easily plugged in to my existing wire harness and BAM! Very happy with the quality of this product for just a small amount of the new cost of an original OEM. No complaints about this at all. 242547
by: Mark K04/24/2015
Nice product for the price. Original equipment was ridiculously priced in comparison. Would like to see a more substantial mounting bracket. The original is MUCH heavier duty. I ended up drilling for holes in the original bracket and mounting whole unit on the original bracket. Much stronger, looks good, and am very happy. 187858
by: Willie J02/16/2015
I contacted etrailer for specific parts needed for my 2008 Tundra. They immediately responded with detailed parts needed for my repairs. They also supplied an installation video as well! A few days later the parts were at my doorstep. Great parts, great service, great prices, great Company! Kudos to the etrailer staff! 174914
by: Brian M07/18/2016
This plug is the perfect fit for my 2007 Tundra. Their website is very informative. This model year has two styles, and etrailer.com was well aware of that and offered photos and advice. My Toyota dealer wanted $200 just for this part! Easy installation and works 100% . I will definitely use etrailer.com again. 273249
by: Chris P.07/01/2015
Being a 1st time customer I am always weary about purchasing items on line, but I was very happy with etrailer & Debbie H. She got my order processed & out the door the same day w/ confirmation. I did have an issue with the product, but it was replaced promptly without hassles ! I will be a return customer. 208621
by: Nick S.02/11/2015
This is a great replacement for only about $35! Plugs right in and is durable. The bracket included seemed a little weak compared to the OEM bracket, but with a 10 minute modification you can use the OEM bracket and not drill any new holes. Excellent choice considering the OEM replacement is over $230.00! 173384
by: Abe H06/01/2016
Perfect ..... Fast shipping also. Moved location of outlets from below the bumper. 255336
Products are good but etrailer shipped them with no manufacturer box or instructions. All they did was remove them from their original boxes and threw them into another box for shipping! No packing material or anything, just a bunch of loose parts rattling away! Pretty sad Etrailer. 20595
by: Brian B.06/21/2015
Great product! Truly plug and play. Just had to unplug the caps from the factory and plug in my new 7-pin. In one of the pictures you can see the plugs. Great product, and great support from etrailer. Etrailer will be my first stop for future trailer accessory purchases. 206073
by: Bill W05/21/2012
As advertised. However the mounting bracket had to be redrilled to match the factory holes under the bumper. Otherwise the connectors fit with the factory wiring and appears to be working fine. It may not be as heavy duty as factory parts but it is also1/6 the cost. 41211
by: Justin Spear03/21/2012
I have to say that it fits great and I was actually able to change the location of it so I will not be breaking it as I have with the one that came with the truck due to poor location and it looks great as if it was designed to be there. sorry I dont have any pics. 34671
by: Jim D in Montana07/11/2016
Scraped off my 09 Toyota Tundra Crewmax female trailer plug in the Mountains. Your replacement matched up perfectly with the male trailer harness connector, was a straightforward installation and your price point was much better than a factory replacement. 270776
by: Peter M08/04/2013
The only issue that I had with this product was that the bracket to attach the wiring kit to the truck did not match(2008 Toyota Tundra). After a couple of modifications, I was able to attach it to the truck. Other then that, everything else fit perfectly. 93194
eTrailer is a very helpful resource in regards to RV parts. I work for an RV dealer and when our main parts distributor doesn't provide the parts we need, eTrailer does! I also appreciate the manufacturer part numbers being included with each part. 356738
by: John R.08/07/2016
Very simple to attach with the quick connect wires. Local Toyota dealership was going to order one for $78 but I found it on etrailer for less than half that price. Easy to locate the correct connection for my truck and very quick delivery. 280882
by: Dan O.04/25/2012
Not excellent, but better than good. Mounting Plate not the right plate for a 2010 Tundra, and holes do not align. Had to bend plate, and redrill holes to larger diameter and placement. Not quite as "plug and chug" as I had hoped for. 38295
As with other reviews I did have to modify mounting bracket. No big deal for a trailer plug that costs 10% of an OEM plug. No problems with ordering. Processed fast with an upgrade on shipping. Thanks. I will order from you again. 82855

Great product good price!!! 133815
by: Jason A09/21/2016
Great harness, easy to install. I mounted it to the left side license plate light hole above the bumper to avoid dragging it on the ground in rough terrain and it fit well. Good product....would recommend it again. 297144
by: Tom b05/31/2013
This is a great replacement trailer wiring harness. Pops right on, and works perfectly. Only reason I'm ordering a second unit is because I broke my first one when a trailer came loose and whacked it. 82698
by: Paul J07/31/2015
Wiring plugged into existing wiring harness. Mounting bracket very flimsy. Also, mounting holes do not match up with the stock mounting holes. Had to make modifications to bracket to get it to mount. 215755
by: Leonard C10/08/2016
Product was exactly what it was supposed to be and delivered to my doorstep quicker and cheaper than the local parts store could get it. I am impressed Leonard C Wenatchee Washington 304629
Product arrived earlier than stated and was quick and easy to install. Customer service was great making an already easy task of finding my part a quick one as time was a factor for me. 342952
Hopkins tow package wiring kit for Toyota Tundra was a snap to install after removing original wiring at the factory connectors the new fit perfectly. Wish all products worked as well. 273958
by: mitchell cozart08/25/2011
very happy with product easy to install worked great.. fast shipping would reccomend to anyone that does not want to mess around with their local dealership and spend way to much money! 22781
Simple to install, plug and play, replacement for my 2007 Tundra trailer attachment. You can't hardly tell it's not OME. Etrailer was great and I got exactly what I was expecting. 292070
by: John R05/17/2011
I made my own bracket for this out of 5052 aluminum, but the connectors are very good quality. Also, the potting on the back of the assembly is WAY better than the factory unit. 14519
by: Terry S12/01/2011
This item was an excellent replacement for the wiring harness on my 2007 Toyota Tundra. The only thing I had to modify was the mounting bracket but the plug ins were perfect. 27523
by: Doug B.12/23/2013
plugged right in to factory connectors. The metal bracket for the wiring harness is thinner gauge metal and required drilling new holes, but great price for what you get. 110964
