Features:

  • 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)
  • Connects quickly and easily - no cutting or splicing
    • Locate connection points at the rear of your vehicle
    • Plug in connector
  • Includes mounting bracket
  • Protective connection terminals resist corrosion

  • 90-Day limited warranty


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.

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:

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:

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:

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:
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:

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



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:
2007 Toyota Tundra

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

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.



by:
2007 Toyota Tundra

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:
2008 Toyota Tundra

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:
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.

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:

Perfect replacement for my oem trailer light receptacle.

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.

Jon E.

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:
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.



by:

Perfect plug and play!!



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:
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!
