  • Provides both a 7-way RV-style and a 4-pole flat connector at the back of your vehicle to power your trailer's signal lights
    • 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.


Vehicle Wiring

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.

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.

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.



by:

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:

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.

@David We're glad it's working well for you!

2007 ToyotaTundra

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:

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

Installed a year ago. Still working good at a fraction of dealership prices. Would definitely buy again



by:

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:
2010 ToyotaTundra

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:

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:

The bracket is not a match- has to be drilled to fit. Cheap hardware in kit, otherwise a good product for the price



by:
2008ToyotaTundra

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:

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:

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.



by:

Works excellent, easy to install, fast shipping, would definitely buy from etrailer again



by:

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.

Perfect ..... Fast shipping also. Moved location of outlets from below the bumper.

2010 ToyotaTundra

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.

Etrailer Expert

Katrina B.

12/8/2022

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.



by:
2007 ToyotaTundra

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.



by:

Perfect replacement for my oem trailer light receptacle.



by:
2008ToyotaTundra

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!



by:

Mounting instructions had it mounted too far back and behind the hitch, so if you live in the mountains, and you get snow banks, its cheap and thin plastic will break the minute you back over a snow bank. Still works, but the plastic cover has holes and cracks. I gave the company a chance to make it right and they said the 90 day warranty is expired on the 1 year anniversary email asking how I liked the product. No discount on another or anything, just pay full price for a new one. No one back their products anymore.

This is a replacement for the OEM harness and will be in the same location. You can use a mounting bracket like part # C57202 to move the harness further out from underneath the vehicle.



by:
2008ToyotaTundra

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.

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.

Jon E.

3/12/2013

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.

Patrick B.

Thanks for the update, glad to have the info.


by:
2008ToyotaTundra

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!

  • How Long Is The Hopkins Tow Package Wiring Kit For Toyota Tundra
    I pulled one of the Hopkins Tow Package Wiring Kits, part # HM11143395 from our warehouse. The harness measures right at 26 inches from the end of the connectors at the end of the harness to the back of the 7-way connector. 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...

  • Availability Of Replacement 7-way Connector For 2007 Toyota Tundra
    I have a replacement option, but the cover on the Hopkins Plug-In Simple Vehicle Wiring Harness for Factory Tow Package - 7-Way and 4-Flat Connectors # HM11143395 you purchased for your 2007 Toyota Tundra is not available as a replacement part. Instead you will need to purchase another # HM11143395 and replace the 7-way connector completely.

  • Is There a Replacement Cover for the Hopkins Plug-In Simple Vehicle Wiring Harness HM11143395
    The cover is not replaceable on the Hopkins Plug-In Simple Vehicle Wiring Harness for Factory Tow Package part # HM11143395. The cover is important because if water gets inside and touches the contacts, it will cause corrosion and short out the lights so I recommend a full replacement.

  • 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. The installation is pretty simple, you can see the procedure by clicking the provided link and viewing the video showing the harness being installed on a 2008 Tundra.

  • 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.

  • 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.

    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...

  • Recommendation for Towing a Trailer with 4-Way with a 2013 Toyota Tundra with 7-Way
    For your 2013 Toyota Tundra I would recommend you replace your current 7-way with a part # HM11143395. This will plug into the factory wiring of your truck and will give you both a 7-way and a 4-way trailer wiring connector at the rear of your vehicle so that you could tow a trailer with either style connector. I attached an install video for this product for you to check out as well.

  • Are the Pins of the Hopkins 7-Way HM11143395 Standard Width for 7-Ways
    The 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.

    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....
