    Great value for a name brand. No fasteners included but pairs great with the no-drill long mount bracket 18136.



    by:

    Worked as it should. Easy install but the plug fits pretty tight into this bracket (as it should).The black finish was really good and did not seem to be cheap. I would recommend this plug mount for the price.



    by:

    Works as intended & provides a nice clean look for the 4pin connector.

    Definitely! It makes a huge difference not having a dangling 4pin.

    Love it. Makes the job look professional, no wire hanging down or attached to the hitch.

    No clutter is the way to go for sure! It looks great!

    Excellent value for a great product! I love how it hides so well under the rear bumper/fascia. They include everything you need for a complete install. Fast shipping and great follow up. The website is so easy to navigate.

    All parts were in stock, located and shipped in a very timely manner. The representative was friendly and knowledgeable about the products which fit perfectly. Looks great! Thank you Cassie at etrailer.com

    Easy mount to keep trailer hitch wiring neat

    Products are great - variety is great - service is second to nobody. Amy is on top of it, and has a great personality. Oh did I mention shipping is excellent.



    by:

    Just as described! I didn’t have to do any Dremel work to get my connector through the slot



    by:

    I great product, bought two of them. great price and fast shipping.



    by:

    The wiring installed very easily as well as the bracket. The hitch was installed
    without issue except for one bolt slot on the on the passenger side. It as the bolt closest to the front. Had I installed the three bolts on the passenger side first, the issue probably would have been on drivers side. The center to center dimension between the
    two slots could have been longer. It just fit. I like it that only the receiver tube show.

    Fits well easy to install.

    I think you got every angle of the install, Andy! I Love it :)



    by:

    It is fine - especially at the price. I wish it was a bit "tighter" pushing a connector on it requires holding it on the back-side



    by:

    I had to modify the mount to fit wiring harness.



    by:

    This with the extending bracket gave the hitch installation a nice finished look.



    by:

    Its good quality but dont need it as my wiring is a 7 pin round. So, I'll save it just in case



    by:

    4 pole connector snaps In nicely. A must have or the connector will just dangle under the vehicle.

    Yes! These are perfect for what they are meant for. Keeps the wiring safer then you don't have to worry about it getting damaged from dragging :)



    by:

    Would have been nice if this was offered when I purchased the receiver and l.e.d. light kit,not making a 3rd purchase for the mounting hardware not included.



    by:

    Perfect fit for draw tite hitch. Didn't include bolts but I had some that fit.



    by:

    Good enough, surprised it doesn’t come with some self tapping screws.



    by:

    These are great quality items at an affordable price. My husband had no problem installing them and he was impressed with how easy it was to put on my vehicle. It looks so good and I can't wait to tow my new camper trailer.



    by:

    Great products. Good installation instructions. Wiring was plug and play.

    I wish you had a bracket to hold the C42CR on top of the receiver like the one I built from 1/2” flat stock. See below.



    by:

    This didn’t workout as well as I had hoped every time I hook up the lights using this holder it slips out of the holder making it difficult to join the two connections together



    by:

    Fast shipping. Package arrived undamaged and was as advertised.

    • Recommended Hitch for a 2023 Lexus RX 350
      The Draw-Tite item # DT73QR installs below the bumper. This hitch is perpetually backordered due to Draw-Tite being bought out so I have a way better option for a hitch for your 2023 Lexus RX 350. I recommend the Curt Trailer Hitch item # C29VV. This hitch is custom fit and bolts to your Lexus with included hardware. I really like this hitch because the crosstube mounts behind your rear bumper leaving only the 2" receiver visible. This not only looks better it also helps with ground clearance....

    • Does the Curt Trailer Hitch item # C13382 Fit a 2024 Subaru Crosstrek?
      Yes, it is accurate. The Curt Trailer Hitch item # C13382 is confirmed to fit all models of the 2024 Subaru Crosstrek except for the hybrids. There was a customer that recently installed this on a 2024 with no issues back in May and he sent me in a picture which I have attached below. No modification or customization needed. It went right on his Subaru. If you are planning on towing you will also need a wiring harness item # C56040 and a ball mount kit item # C45534. I recommend using...

    • Recommended Hitch and Wiring Harness for a 2022 Toyota Highlander
      Hey Joseph! The Curt item # C45CR requires you to disconnect an exhaust hanger temporarily, but it gets reinstalled a couple steps later. It's just to get the hitch to the mounting bolts behind the muffler. This hitch is custom fit for the 2022 Toyota Highlander and fits all models including your Platinum. For a 4-way wiring harness, you'll want the T-One Vehicle Wiring Harness item # TK99FR. This custom fit harness plugs directly into the existing wiring of your Highlander without requiring...

    • 2019 Hyundai Ioniq Plug-In Hybrid Wiring Kit Recommendation for Thule Bike Rack Tail Lights
      We do! I recommend picking up the Tekonsha T-One # 118758 for your 2019 Hyundai Ioniq Plug-In Hybrid and securing it by your hitch receiver with the mounting brackets # C42CR and # 18140 so the 4-Way is easily accessible. If you have the Thule Epos bike rack then you're needing the License Plate and Tail Light Kit # TH79XE, otherwise I recommend going with the Curt Auxiliary LED Indicator Lights # C53201 since they come with an adhesive that makes them quite easy to install. If you don't...

    • Recommended Hitch and Wiring Harness for a 2002 Mitsubishi Montero
      Hey Rene, thanks for the information. To add a hitch to your 2002 Mitsubishi Montero, you'll want the Curt item # C13800. This is a class III, custom fit hitch with a 2" receiver, that includes all necessary hardware to bolt onto your Montero. It will not fit the Sport models and I do not have an option for a hitch that does. For a wiring harness, I recommend the Curt T-Connector item # C55380. This custom-fit T-connector plugs into your Mitsubishi's wiring harness, which is located behind...

    • What do I Need for My 2021 BMW X3 M40i so I Can Tow a 6x12 Trailer to Move to a Different State?
      Hello Michael, Happy to get the right tow package together for your move to a different state. I would like to mention that just because the hitch is rated for a specific weight does not mean your car can tow that much, you will need to check your owners manual to see what BMW says you can tow, you are only as strong as your weakest link. The highest rated hitch we for your 2021 BMW X3 M40i is the Draw-Tite Max-Frame Trailer Hitch Receiver - Custom Fit - Class III - 2" # 76226. For...

    • Can I Install Both a Flat Towing Wiring Harness and a 4-Way Connector on a 2018 Jeep Wrangler JK?
      Yes, so long as you don't try to use both of them at the same time. The Curt T-Connector Vehicle Wiring Harness item # C55124 will work as a 4-flat connector and plugs into your Jeep's existing wiring. If you try to flat tow your 2018 Jeep Wrangler JK with say a bike rack on the back or a cargo carrier that has lights on it then the 4-flat connector will not work, only the Hopkins item # HM56200. The Curt item # C55124 is confirmed to fit the 2018 Jeep Wrangler JK's without the towing...

    • Can I Still Use the Kick Sensor when I Install the Draw-Tite Hitch on My 25 Toyota Grand Highlander?
      Hello Gene, Yes, your kick sensor will still work after installing the Draw-Tite Max-Frame Trailer Hitch Receiver - Custom Fit - Class III - 2" # DT95PR. It might block the sensor slightly, so you may need to kick your foot to the right or left of the receiver to find the sweet spot, but it will still function. If you're looking for some wiring to pair with the hitch for light towing or a hitch-mounted accessory, you'll want the Curt Powered Tail Light Converter with 4-Pole Flat Trailer...

I wasn't sure if you meant a 4-flat wiring harness or the bracket to mount a 4-flat (or both), so I included options for both! : P Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56040 Curt Mounting Bracket for 4-Pole Flat Trailer Connector # C42CR The wiring bracket on the # BLU73UR hitch you ordered for your 2022 Subaru Crosstrek (non Hybrid) measured a smidge over 1.5 inches center to center on the mounting holes (1.58 inches to be exact)....

    • Does the Curt Hitch C13409 Block the Liftgate Sensor on a 2025 Subaru Forester?
      Hey Will thanks for the question! The Curt Hitch item # C13409 is compatible with the automatic tailgate switch on your 2025 Subaru Forester. You'll lose some of the sensors range around the 2" receiver but you're not going to want to be kicking in that area anyways once you get it installed. What do you plan on using your hitch for? If you are planning on towing you will also need a wiring harness item # C56040 and a ball mount kit item # C45534. I recommend using the No-Drill Mount...

      Yes, it does. The Curt Hitch 13493 or our part number item # C76WR is confirmed to fit the 2024 Ford Bronco. This hitch is custom fit and bolts to your Bronco with included hardware. This is a class III hitch with a 2" receiver. It has a 3,500 lbs towing capacity and 350 lbs maximum tongue weight. I really like this hitch because of how easy it is to install it. You only have to install four bolts to your rear bumper to get this hitch set up. I have linked an installation video below along...

    • Will an Aftermarket Hitch Get in the Way of My Hands Free Tailgate Sensor on 2025 Toyota Rav4?
      Hello Hal, Congrats on the new ride! What is your favorite new feature? With any aftermarket hitch there is the possibility that the hands free tailgate sensor will be covered. So if you install B&W Trailer Hitch Receiver - Custom Fit - Class III - 2" # BW47BR on your 2025 Toyota RAV4 it is possible to lose full capabilities of your hands free tailgate, in our experience you can usually maneuver your foot to the right or the left of the receiver to have the sensor work.

It has a 5,000 lbs towing capacity and a 750 lbs maximum tongue weight. I really like this hitch because the crosstube mounts completely behind the rear bumper leaving only the 2" receiver exposed.

      Hey Shannon! I'll start by confirming that the EcoHitch Hidden Trailer Hitch item # 306-X7219 will fit the 2017 Toyota Rav4 Hybrid. Out of those two wiring harnesses, I recommend going with the Curt item # C56350 over the Tekonsha item # 118578 because of reliability. This custom-fit T-connector plugs into your Toyota's wiring harness, which is located in your rear cargo area. It will provide you with a 4-way connector.

    • Is there a Mounting Bracket that Will Attach a Wiring Harness to a Hitch w/out Drilling?
      Yes, we do! The best one is going to be the No-Drill Mount for Electrical Mounting Bracket item # 18140. This bracket will wrap around any hitch, square, round, OEM, or aftermarket and provide you with a mounting point that does not require drilling. You can use the Mighty Cord Universal 7-Way Mounting Bracket item # A10-9394VP for a 7-way connector or item # C42CR for a 4-way if your connector needs an additional bracket.

      Hey Vincent. As of 5/8/2025 there are no plug in wiring harnesses for a 2025 Kia K5. The only option I have today is the ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit item # 119250KIT. This kit uses sensors that clamp onto your K5's taillights without splicing into them. The sensors detect the current and activate your trailer's lights through the 4-way connector.

    • On Your etrailer Hitch for My 2025 Subaru Outback Why do I Need the Carriage Bolt Through the Frame?
      Hello Stanley, Congrats on the new 2025 Subaru Outback! What is your favorite new feature? I watched the video and see the bolts you are referring to. I get what you are saying, seems a little excessive to have the bolts thru the bumper, and underneath as well. That carriage bolt you saw in the video helps anchor the side arm of the hitch to the frame for extra stability. While most of the hitch is secured to the bumper beam, this bolt keeps things from flexing or shifting side-to-side,...

      I have attached an installation video of the # 118258 wiring harness on a 2009 Hyundai Santa Fe for you. The installation is pretty straight forward once you have gained access to the factory connectors. To do this, you are going to start by lowering the spare tire, and then you would open up the cargo area and remove the access panels, threshold trim, trunk floor panels and trays. Proceed by removing the trim panel on the driver side, but make sure you remove the fastener on the driver...

    • Best Way To Remove 4-Flat Plug From Curt 4-Way Flat Mounting Bracket C42CR
      Hello Dennis, thanks for reaching out. The best way to remove the 4-flat plug from the # C42CR bracket is basically the same way it went it. I would start by working the plug from side-to-side a bit to get it loose. Then press the plug out thru the back of the bracket. Try pressing with your thumb while working the plug side-to-side and it should come out with a little persuasion. If it is stuck in there real good you could maybe try some lubricant spray or WD40 to help move things along.

      Yes, there is Steve! We had a customer run theirs through a rubber grommet in the wheel well. If you can't find an opening in yours there's typically a drain type plug that's sealed up underneath the spare tire. This will let you route the Curt T-Connector Vehicle Wiring Harness item # C56370 below your 2023 Honda CR-V. You'll just need to search around and see where the factory wiring goes but there's plenty of length in the harness. I recommend using the No-Drill Mount Bracket item...
