- Designed for use with a factory tow package
- Compatible with 5-pole and 6-pole adapters (sold separately)

Installation
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.

Toyota Tundra
This wiring kit feels cheap, but that’s why I came to Etrailer - Toyota wanted $500 +.
I put this on a Toyota Tundra and the wiring matched as should, I drilled the mounting bracket to match Toyota instead of clamping it to the hitch. Overall, it worked as should. I’ve only pulled a couple trailers with it, but was pleased it worked well. It did get some moisture in it though while pulling in rain. Not sure why, but I’m not going to say it was because of this plug, as there were a few other variables. You get what you pay for, but I am pleased mostly that I didn’t have to spend $500.

Bought it for my 2007 tundra trd sr5 with the tow haul package. Plug and play just like the team said. Had to drill out the holes for the mounting bracket a little and straighten the bracket as well but very happy with my purchase nonetheless and will definitely come back here if I need more parts.
by: David11/08/2022
Works great. I cut a hole in my rear bumper and mounted it there. It used to be mounted below the bumper and kept being hit and bent went I went anywhere off-road. Now I'll have to tear off the bumper before I can damage it ;-)

The connector is still working great and by moving it to the bumper it is more convenient to use and safe from being whacked when off-roading.

Excellent! Plugged right into factory wiring back to connector. No more coroded original wiring.

2007 Toyota Tundra
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:

2010 Toyota Tundra
Quality plug, and a perfect fit for the factory trailer wire connectors on my 2010 Tundra. I had to bend the mounting brackets a bit to get the plug to clear my Curt XD hitch, but the result is sturdy and looks good. etrailer was great to work with -- shipping was prompt, updates and tracking info was provided, and the item was as described.
by: Enrique06/09/2020
Needed Oem replacement for my Tundra traile connector and this almost fit like a glove/ no complaints. I do wish it was more “metal” vs plastics but it is what it is and overall it connected perfectly and the wires are a little stiff to work on the hitch; but all is good.
by: Nick07/02/2022
These plugs worked great on my 2010 Toyota Tundra. I was having problems with running lights on my trailers not working on my stock plugs but once I installed the new plugs I have had no issues. Also I moved the plug location to up beside the license plate like many of the newer trucks on the market today. I would and have recommended these plugs to others.
by: Eddie03/06/2021
2008 Toyota Tundra
Impressed by this. The plugs matched the OEM connection perfectly. I am impressed. I relocated the broken OEM trailer plug to next to the license plate. I never liked how trailer plugs have historically been located on or near the reciever.
Would definitely recommend.
by: Justin B02/14/2014
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!

so far so good. its still working and I am happy with it.
by: Brent08/25/2023
The bracket is not a match- has to be drilled to fit. Cheap hardware in kit, otherwise a good product for the price
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.

Plugged right in to the connectors. I didn’t use the bracket I wanted to get it up higher so I bumper set it. So far great purchase.

Install was easy, great product and fast delivery. I adjusted the mounting bracket to fit the way I wanted it to look but other than that I would recommend to others.

2010 Toyota Tundra
The installation is easy and straightforward, but my trailer plug fits so loosely that the 7-way part of the plug comes disconnected just enough for the lights on my trailer don't stay illuminated. I'm disappointed in the receptacle fitment.
Katrina B.

This is very unfortunate that this plug is not fitting as intended. There doesnt seem to be any obvious molding issues, so there shouldnt be any problems with the plug fitting. It could be that something inside the receptacle is blocking the 7-blade trailer plug from fully nesting. This could either be a bent pin, or something else inside the receptacle itself.

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!

2008 Toyota Tundra
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.

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.

2008 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 etrailer.com

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.

2008 Toyota Tundra
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.

No problems. Working great!
by: Paul08/18/2020
Exact fit for my 2007 Tundra. This is a high plug and play replacement for the Toyota part at way, way less cost. Hard shell plugs connecting to the chassis harness have silicon seals and the leads into the rear of the 7 way are potted. Leads are the same colors as OEM and everything tests out. My neighbour who also had to have his harness replaced (2008 Tundra) asked me to buy one for him as well. Being in Canada it was nice to see that the shipping costs are also very reasonable compared to some US sources.
If you are Canadian, you should check these guys out.

Installed this about a year ago. Continues to work just fine. No issues with sealing. Great product. No complaints.

- 5th Wheel and Gooseneck Trailer Hitch Wiring Recommendation for a 2009 Toyota TundraProvided 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.

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...

- Replacement 7-Way Wiring Harness for a 2007 Toyota TundraSince 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.
view full answer... - 4-Way And 7-Way Adapter For 2014 Toyota TundraIf you have a 7-way connector on your 2014 Toyota Tundra, the harness I recommend is the Hopkins Custom Fit Vehicle Wiring, part # HM11143395. Both the 4-way and the 7-way connector are active at the same time on the harness. You may want to check your Tundra owner's manual for any information as to its wiring capacity to avoid any potential for overloading the vehicle circuit.

Instead you will need to purchase another # HM11143395 and replace the 7-way connector completely.
view full answer... - Replacement 7-Way Trailer Connector for a 2007 Toyota TundraFrom 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...

- Replacement Trailer Wiring 7-Way Recommendation for a 2008 Toyota TundraThe correct replacement 7-way you would need for your 2008 Toyota Tundra is the Hopkins 7-Way part # HM11143395. I attached an install video for this product on a very similar 2008 Toyota Tundra as yours as well.
view full answer... - No Power at 12 Volt Pin In 7-Way on a 2008 Toyota TundraThe first step I would take would be to check the 30-amp trailer brake controller fuse which is located in the # 10 slot on the fuse box under the hood of your 2008 Toyota Tundra. If the fuse is still intact, then you will want to move to the 7-way trailer connector. Using a circuit tester like part # PTW2993, check the black wire on the back of the 7-way way while the vehicle is running. If you are getting power here then the problem is in the trailer connector, and it will need to be...
view full answer... - Installing OEM Replacement 7-Way Trailer Connector on 2007 Toyota TundraThe correct replacement 7-way for your Tundra should be part # HM43385. You can confirm this by examining the connectors under the truck that the connector would plug into. One connector should accept 4 pins, the other three pins. If your connectors are different, with one accepting 4 pins and the other 2 pins, you would need # HM11143395. The HM43385 fits 2003-2007 Tundra models, according to Hopkins. It is important that you check the existing connectors to ensure you get the correct...

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...

- 7-Way Trailer Wiring Harness Recommendation for 2008 Toyota TundraLooks like you broke the 7-way of your 2008 Toyota Tundra.

I attached an install video for the harness on a similar 2008 Tundra as well.

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...
view full answer... - 4-Way and 7-Way Recommendation for a 2008 Toyota TundraYes we have exactly what you are looking for. You would want the Hopkins part # HM11143395. This is a 4-way/7-way connector that will connect to the two connectors you have at the rear of your vehicle and will provide you with both types of connectors that you are looking for. I attached an install video that shows this connector being installed in a 2008 Toyota Tundra like yours.
view full answer... - Are the Pins of the Hopkins 7-Way HM11143395 Standard Width for 7-WaysThe pins of the Hopkins 7-way part # HM11143395 that you referenced are standard in size and would work with all standard 7-way plugs. I could see a narrower pin setup still working too since it's all about making contact but there's no reason to be concerned with the pin width of the # HM11143395.

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...

- Replacement 7-Way and 4-Way Trailer Connector for a 2007 Toyota TundraWe 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...

- Brake Controller Recommendation for a 2014 Toyota TundraYou would want to install a brake controller. You should check with your local laws and regulations to determine what towing setups are required to have trailer brakes activated by a brake controller. Some states require trailer brakes and a brake controller on any vehicle that is towing a trailer, but in your situation I would strongly recommend one. We recommend that at the very least if the trailer weighs over 50 percent of the weight of the tow vehicle than a brake controller should...

You would just need to unplug the old connector and install the # HM11143395. When working with electrical connectors I recommend using dielectric grease like part # 11755. This keeps dirt and moisture out of the electrical connections and helps prevent corrosion.

- Replacement 7-Way Trailer Connector-2007 Toyota Tundra The Hopkins # HM11143395 you've looked at is the correct replacement 7-way for your 2007 Toyota Tundra.

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...

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 # PTW2993. 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...

Still works after a year. It is not OEM replacement, but it does the job. Have put a few thousand miles of traveling with the 7 pin and the 5 pin, both work as should. No problems.
