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.

Video Transcript for Hopkins Custom Fit Vehicle Wiring HM11143395 Review

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. .

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 80497


After a year of use there are no issues with the harness or its use. This was and is a good product and I am very happy with it! Thanks etrailer.

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


Just an update with my 2007 Tundra, double cab, SR5, build date 807. I did install the HM11143395 as noted above . I have hooked the truck up to six different trailers and the lights all work properly.I also see etrailer added a video on the running change by Toyota on the 2007 Tundra.

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


so far so good. its still working and I am happy with it.

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


Product working just fine no corrosion issues and remains rigidly affixed.

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


No problems. Working great!

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: 116629


Here is a link to the bracket Rick used to mount this 7-Way.

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


After doing a lot of trailering last summer, and some sporadic trips this winter, I can happily say the wiring harness is working just fine. I hope it continues, and I have no concerns!

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

Tried plugging the wired sockets in and the plugs are correct for my truck. Seems the 2007 Tundra did a change on the trailer wiring connectors during production but mine is a later one, (Feb) so it worked fine. Haven't actually mounted it yet as I want to try to put it in the bumper instead of it's original location where it seems to like to get smashed. My bumper is gnarly so it is a good one to experiment on. There seems to be enough room left of the license plate. 390798

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

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

by: David08/21/2015

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

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

- HM11143395

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 to anyone. 15493

The Harness itself is fine. The Bracket that came with the harness has the mounting holes at 90 degrees to the 7 way. On my 2007 Tundra the mounting holes need to be straight up from the 7 way. Bending the bracket would solve the problem, but I assume would weaken the bracket. I am going to investigate mounting the 7 way through the bumper as others have done. 379795

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

This plug is the perfect fit for my 2007 Tundra. Their website is very informative. This model year has two styles, and 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 again. 273249

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

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: Justin S08/09/2017

The product was great but I assumed it came with all of the parts that make it work for the truck. So now I have to buy a universal mounting bracket to make it all work. I wish it would have had that somewhere in noticeable writing so I would have known that before I bought it. 417959

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

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

  • We do have a replacement 7-way and 4-way trailer connector for the 2007 Toyota Tundra, but before we can determine which harness will work for your truck, we will need to know what type of plugs your trucks tow package wiring requires and how the connectors are wired. Unfortunately, Toyota decided to wire this truck a number of different ways. The Tundra had a generation change between 2006 and 2007 and this caused some discrepancies in the wiring. Your factory 4-way and 7-way trailer...

  • 7-Way Wiring Harness Recommendation for a 2012 Toyota Tundra with a Factory 4-Way
  • I wish I had a plug and play 7-way that would install on your 2012 Toyota Tundra that would replace your 7-way. But you will need to hardwire in a 7-way. If you only need a 7-way for a trailer without trailer brakes you could get away with just getting a # 37185 and just plugging in your 4-way to it. If you need to install a brake controller and operate trailer brakes you will need to get a Brake Controller Installation Kit part # ETBC7. This comes with everything you will need to install...

  • Replacement 7-Way Trailer Connector for a 2007 Toyota Tundra
  • From what I could find, the 2007 Toyota Tundra used a harness like the 2006 model, # 20137. However, the plugs in this replacement connector do not sound like what you are describing. What you are describing sounds like the harness for the 2008 to 2010 models, # HM11143395 that you have referenced. Also, for a 2007, I found that a harness like # 54701-004 will fit and it has connectors like on # HM11143395. You will need to examine your connectors closely to determine which one, # 20137...

  • Trailer Hitch and Wiring Recommendation for a 2010 Toyota Tundra TRD SPORT
  • I spoke with my contact at Draw-Tite and he stated that hitch # 41935, fits all models of the 2010 Toyota Tundra, including the TRD Sport models, as long as it did not come with a factory trailer hitch. You could also use Curt trailer hitch # C15398. I have included links to the installation instructions for each for you. If you plan on doing some towing, I recommend the etrailer ball mount kit # EBMK2416. It comes with a ball mount, 2 balls, a hitch pin with clip, and a carrying bag....

  • Wiring Harness and Brake Controller Fit 2013 Toyota Tundra
  • In order to determine if you can use the Hopkins Tow Package Wiring for Toyota Tundra # HM11143395 that you referenced, you will first want to check for the mating connectors at the rear of your truck, near the bumper. If your Tundra has the mating connectors, one with 5 pins and the other with 2, you will want to use a circuit tester, like # 40376, to test the functions of each of the pins on the vehicle connectors. I have attached a photo of the connectors on the wiring harness with...

  • Installing Hopkins Tow Package Wiring Kit # HM11143395 on 2008 Toyota Tundra
  • The Hopkins Tow Package Wiring you referenced, part # HM11143395 will plug into the trailer wiring connectors located under and behind the rear bumper. The connectors are usually found over toward the drivers side frame member. If the controller is already installed using a wiring adapter like # 3040-P, you should be all set to go. Make sure that the extra ground wire on the adapter is securely attached to a factory grounding point under the dash. You can see an install video showing...

  • 5th Wheel and Gooseneck Trailer Hitch Wiring Recommendation for a 2009 Toyota Tundra
  • Provided that your 2009 Toyota Tundra has a factory 7-Way trailer wiring harness at the rear of the truck, you can use 5th Wheel and Gooseneck 90-Degree Wiring Harness with 7-Pole Connector, # 51-97-412. This harness is designed specifically to be mounted in the bed of the truck for 5th wheel or gooseneck trailers and connect in line with the factory wiring on your truck.

  • How to Identify a Trailer Connector on a 2009 Toyota Tundra
  • If your 2009 Toyota Tundra came with the factory tow package, then it should have a 7-way round trailer connector attached to the bottom of the rear bumper to the left of the trailer hitch (see photo). I recommend looking at the back of your truck to see if you have the factory 7-way trailer connector. If your truck does not have a 7-way trailer connector and you are sure your truck was equipped with the factory tow package, there should be two connectors under the vehicle near the frame...

  • Brake Controller Wiring Adapter for 2012 Toyota Tundra
  • The proper brake controller wiring adapter is # 3040-P, which would plug into the connector located to the left and above the emergency brake pedal, as shown in the photo I provided. If your truck doesn't have the 7-way connector, you can install one using part # HM11143395 which plugs into the connector located behind the rear bumper of the truck. If you have the older version Pilot brake controller that simply has the bare wires exiting the rear, you'd cut the black plug off your 3040-P...

  • Will Hopkins Plug-In Simple Vehicle Wiring Harness # HM43385 Replace Factory Toyota 7-Way
  • If you have a 2003-2006 Toyota Tundra the 7-way wiring harness part # HM43385 that you referenced would essentially be the exact same thing as going with the Toyota brand connector. Most likely the Toyota connector does not have the 4-way option that comes with this as well. This will most likely be less expensive too.

  • 7-Way Trailer Socket for 2012 Toyota Tundra with Factory Tow Package
  • The part you referenced, Pollak 7- and 4-Pole Trailer Connector Socket with Mounting Bracket # HM40975, accepts a standard round U.S. Car connector which is the type supplied on the 2012 Tundra with factory tow package. Please see the linked photo showing the rear side of this item. As long as your truck has the round connector to mate with this socket it will serve as a suitable replacement. If it does not have a round U.S. Car connector, but instead has two small square and rectangular...

  • How Does the Hopkins Tow Package Wiring Kit # HM11143395 Install On a 2010 Toyota Tundra
  • As long as your 2010 Toyota Tundra has the factory tow package 7-way connection harness underneath the rear of your truck this would simply plug in and you would be ready to go. However, if you do not have the factory harness you will still be able to plug this unit in. I would recommend plugging the Hopkins Tow Package Wiring Kit, part # HM11143395, and testing the wires to make sure the tow package is complete. If you have a 4-way trailer connector and you are looking upgrade to a...

  • Which Replacement 4-Way and 7-Way Trailer Wiring Harness for a 2007 Toyota Tundra
  • The part you have selected, the Hopkins Tow Package Wiring Kit for Toyota Tundra, part # HM11143395, is specified for 2008 - 2010 Toyota Tundra trucks. This part has two grey connectors to couple with the factory wiring; one is a 2-wire rectangular connector and the other a 5-wire square connector. It will be a good idea to inspect the existing connectors on your Tundra to confirm the number of wires going to each so that you are certain of the replacement. Toyota did make some running...

  • Replacement 7-Way Wiring Harness for a 2007 Toyota Tundra
  • Since your truck has a 5 pin plug and a 2 pin plug for the trailer connector, you will want the Hopkins Tow Package Wiring Kit, # HM11143395, that you referenced. Toyota made a change to the tow package wiring during the 2007 model year, so some 2007 models, like yours, are wired like the 2008 - 2010 models.

  • Adding a 4 and 7-Way Trailer Connector to a 2007 Toyota Tundra
  • In order to install a 7-Way trailer connector on a 2007 Toyota Tundra, it would be a hardwire situation, as the HM11143395 will not fit. Instead you would need to have a 4-Way or add a 4-Way using # 119179KIT, and then use a 4 and 7-Way installation kit # ETBC7. I have included a link to the installation details for the 4-Way and links to an FAQ and video showign the installation of an ETBC7 kit. If you need a brake controller, I recommend the Tekonsha P2, # 90885. It is one of our best...

  • What 7-Way And 4-Way Connector Will Replace Existing 7-Way On 2008 Toyota Tundra With Tow Package
  • For your 2008 Toyota Tundra with factory tow package you will need to use the Hopkins Replacement Multi-Tow 7-Way and 4-Way Trailer Connector # HM11143395. This will plug into your factory tow package wiring harness and give you a 7-way and 4-way at the rear of your vehicle. It looks just like the # 20137 picture, but has a different connector for the 2008 to 2010 Toyota Tundra. The Tow Ready Replacement Multi-Plug 7-Way and 4 Pole Trailer Connector, part # 20137, is for the 2003 to...

To finish the installation of your brake controller on your 2008 Toyota Tundra with a factory 4-flat, you can use our Brake Controller Installation Kit, # ETBC7, or purchase individual parts as needed. Hopefully the 7 way connector installed by the previous owner has a connection point for the factory 4-Flat...

  • Will Hopkins Tow Package Wiring Kit # HM11143395 Work with a Canadian Truck
  • I spoke with my contact at Hopkins who said this part is designed to fit the 2007 to 2014 Toyota Tundra with the factory 7-way. If your 2014 Tundra came equipped with the factory 7-way plug -- the same configuration as in the photo I have attached -- then # HM11143395 is the part you want. My contact said Hopkins has not had any fit issues with Canadian models.

  • Troubleshooting Trailer Connection and Instrument Panel Lights on 2007 Toyota Tundra
  • It can be a bad ground. I recommend that you check the trailer connector for corrosion as you mentioned, but also check the ground on that 7-way connector. It should be metal on metal and free of corrosion and debris. Clean up your 7-way terminals with a small brush and see if the issue is resolved. It sounds like you have the issue even then the trailer isn't connected, but if it only happens when the trailer is connected, then check the main ground on your trailer in the same way....

  • Troubleshooting Trailer Turn and Brake Lights that Stopped Working with 2007 Toyota Tacoma
  • Since the same turn signal and brake light issues occurred on two different trailers, it certainly appears that the issue is on the vehicle side of your Toyota Tacoma. As all the fuses are in good shape, I recommend going to the trailer connector at the rear of your Toyota Tacoma to test the pins with a circuit tester like # 3808. You can have a buddy sit inside the cab and go through the various light functions as you test the corresponding pins for power. If you are not receiving...

  • Replacing Existing 4-Pole Trailer Connector on 2011 Toyota Tundra with a 7-Way
  • You'll need to convert your existing 4-pole to a 7-way trailer connector. How to go about this will depend on how your truck is equipped. Follow the wire from your existing 4-pole, and find the connector it plugs into just behind the bumper. If there's a second connector right next to it, and there's wires leading to the connector, you'll be able to unplug your existing 4-pole and use the # HM11143395 instead. If you were wanting to install a brake controller, you'd need to choose a controller...

This comes with the mounting bracket and hardware needed to install on your 2007 Tundra. You can easily connect this harness to the plugs that are located behind the 7-way on your Tundra behind the rear bumper. I have attached a short video that shows the dimensions...

  • Brake Controller and Weight Distribution for 2012 Toyota Tundra Towing Keystone Outback TT

Proportional controllers offer safe predictable braking and the P2 is extremely easy to set up and use. If your Tundra has the factory installed 7-way, you'll need the brake controller wiring adapter, part # 3040-P. If the truck has the 4-pole connector, you'll unplug the 4-pole and install # HM11143395. If it has no controller at all, you'd install the # HM11143395. To choose a weight...
