    Guys, I can't get past the horribly bad packaging for this shipment. I was away when this arrived at my house. My neighbor was kind enough to put the box in my garage. He sent pics showing the horrible condition of the box and that the trailer hitch had poked out of several areas. I have yet to open it, but have to assume the contents are damaged and may have some parts or hardware missing. THE BOX THIS WAS SHIPPED IN WAS NOWHERE NEAR BEING UP TO THE TASK!!!!

    Yikes! It does indeed sound like the box had a rough trip. I will have our Customer Service team contact you. If anything was damaged or lost when we can replace it.



    by:

    this bracket holds the flat plug exactly as it should and it mounted to the supplied bracket on the hitch



    by:

    etrailer.com is consistently awesome! Not only do they have the parts I want at prices I feel are fair, but they've got a ton of great review and installation videos that are super helpful.



    by:

    Was advise the originally ordered part was on back order, switched to this item per etrailer recommendations. arrived very quick, and went together as advertized. What a GREAT bunch you have there. thanks for looking out for me, and ps I saved some money using the recommended replacement.
    GOOD JOB!!



    by:

    It's worth the money to purchase this when installing the receiver. It gives the receiver a clean look! No hanging wire harness! Thanks again Etrailer!



    by:

    Item #C42CR was not in the delivery package. It has not been received.
    The hitch was received in good order and was installed as hoped. I am extremely pleased with the tow hitch. I highly recommend it.

    Great to hear that about the hitch! I will have our customer service team reach out to you about the missing bracket.



    by:

    All items were in same box with the tail lights loose in the box. Gladly the lights were not damaged. I'm hoping this way of shipping is not typical for trailer. Thanks



    by:

    Follow the great video that is available thru etrailer website and you will not have any install issues..purchase the wiring kit and bracket and the install will go as planned. The products are built to last and fit is perfect..
    READ AND FOLLOW THE INSTRUCTIONS before install...



    by:

    Great product. Right price, fast delivery, and quick response time. Thank you.



    by:

    The bracket worked perfectly



    by:

    No mounting hardware included with this product. I have to go to ACE to purchase the mounting screws, washers and nuts.



    by:

    It doesn’t come With the self driving screws, but the bracket was perfect for what I needed. Fortunately I had some self driving bolts that worked perfectly. I believe 7/16 or 3/8 was the size of the self driving bolts that I used



    by:

    Fine bracket - holds 4 pin connector se curely.



    by:

    The etrailer components and install guide worked perfectly. Saved me hundreds from local retailers.



    by:

    I'm going to tap two screw holes in beam and attach curt mounting bracket. It would be nice if the holes were included with the trailer hitch.



    by:

    This mounting bracket is great for securing the flat 4-wire connector. It looks very factory!



    by:

    Hot trash. Absolutely does not fit the 4 pin y'all sold me. Shameful.

    I hate to hear that it is not fitting. I want to help and I have a question for you. Is it that the bracket is too small or too big? If the bracket is too big, you can use electrical tape to thicken the four way connector to help it stay in. Or if it is too small then I recommend using a different bracket such as part # HM48595 to hold the 4 way in place. It is also made by Hopkins so it will fit.



    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:

    I WAS GOING TO GET A HITCH FROM ANOTHER COMPANY THAT SELLS AND INSTALLS HITCHS [AND RENT TRUCKS AND TRAILERS]. THEY MADE IT SEEM THAT IT WOULD BE DIFFICULT TO MYSELF, AND THEN I DID SOME LOOKING ON YOUR WEBSITE, AND WATCHED YOUR VIDEO. YOU SHOWED STEP BY STEP ON WHAT DO. TOLD ME TO LOOK FOR WIREING HARNESS THAT HAD A PLUG TO PLUG YOUR WIRE TO. EVERTHING WAS JUST AS HE SAID, IT TOOK ME 1 HOUR TO INSTALL HITCH AND WIRE HARNESS, SAVED ME AROUND $[XX], THANK AGAIN.



    by:

    Easy and simple. Only gave 4 stars because item did not come with mounting bolts. Easy fix with bolts I had on hand. No drilling required because it was compatible with the Draw Tite Class III (76034) I also purchased from etrailer.

    Javi

    3/10/2022

    No issues since the day I mounted it.



    by:

    Worked great I ordered the universal mount for it also, but did not use it. I put the Draw Tite undermount hitch on Grand Cherokee last year and didn't realize it had the mount welded on it. Advice check yours before ordering.



    by:

    This does the trick. Looks factory and is easy to install. Definitely recommend using this for wiring you trailer hitch plug. Clean installation and looks great.



    by:

    This does not work with Tekonshea 4 pole connectors that are tapered. It will not lock into place. Additionally, it does not come with any self tapping screws or anything to attach this to the hitch. I would not recommend this.

    It is not the first time we have heard this. Sometimes it happens with these types of four flat bracket no matter the brand. I recommend using electrical tape to thicken the four way connector to help it stay in. You are correct in that I wish the manufacturer would include hardware with it. Or you can consider using this with a no drill bracket like part # 18136 or part # 18140.



    by:

    I’m sure it’s a good piece. My curt hitch is round. Bumper is plastic so I didn’t want to secure it to that. I went and looked at reviews and saw a video that shows a long bar with a strap that it was attached to to secure it. Wish I had seen that when I was ordering.

    A strong and versatile bracket to mount a 4 prong trailer connector.
    Quick and easy online ordering.

    • Where Is The Factory Trailer Connector On A 2023 Buick Envision
      Yes the factory trailer connector will be located behind the center of the rear bumper. It should be a square shaped plug with 4 pins. Once you locate it you can plug in the Curt wiring harness # C56325 and you will be good to go. It is recommended to get a bracket like # C42CR to secure the connector.

    • Recommended 4-Way Wiring Harness for a 2023 Jeep Wrangler 4xe
      Yes, and it should if you have a 4-way connector on your cargo carrier. The T-One Vehicle Wiring Harness item # 118786 is confirmed to fit the 2023 Jeep Wrangler 4xe. This custom fit T-One connector plugs into your Jeep's wiring harness, which is located behind the tail lights.

      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...

    • Is There A Wiring Mounting Tab On the Hidden Hitch Like The OEM Hitch for My 2004 Lexus RX330
      There is no tab on the Draw-Tite, item # 75153, for mounting the wiring harness. We do carry mounting options for the wiring on your vehicle. For the 4-way trailer connector you can use theCurt Mounting Bracket for 4-Pole Flat Trailer Connector Item # C42CR. If you have a 7-way connector then you can use the 6 and 7-Way Trailer Connector Mounting Box for Round Tube Hitches, item # 18159, which works very well with the round tube hitches.

    • Recommended 4-Way Wiring Harness for a 2017 GMC Terrain w/out the Factory Towing Package
      I would be happy to help clear up the confusion. Since your 2017 GMC Terrain does not have the factory towing package you will need the Curt T-Connector Vehicle Wiring Harness item # 56094. This custom-fit T-connector plugs into your vehicle's wiring harness located behind the tail lights. This harness only works on the Terrain's without the towing package.

    • Recommended 4-Way Wiring Harness for a 2023 Acura MDX
      As of (7/31/23) there are no custom fit wiring harnesses for a 2023 Acura MDX. To add a 4-way harness you will need the Curt Powered Tail Light Converter item # C59236. This is a universal harness so you will have to cut and splice wires. I also recommend using the No-Drill Mount Bracket item # 18136 and the item # C42CR to secure the 4-way connector to your hitch. This will put it in an easy to reach spot and prevent the risk of it falling onto the road.

    • What Trailer Wiring Bracket is Recommended for the 4-Way to 5-Way Adapter TR20046
      The # 47515 would be a bit too thin to fit the # TR20046 perfectly so a better option would be the # C42CR which is just a bit smaller and should work.

      They actually are not, but fret not! The Draw-Tite Max-Frame Trailer Hitch # 75713 will utilize existing bolts on your 2018 Dodge Durango. If you watch the install video I have included below, it will show you exactly where these bolts are located. It's a total of 4 bolts (2 bolts on each side of the vehicle), so it will be a pretty quick and straight forward install as well. Install instructions are also included below.

The Draw-Tite has a hidden crosstube and is a very reliable trailer hitch while the Curt T-Connector tees in behind your tail lights and draws power directly from your vehicle battery with the included black wire to keep your OEM wring safe.

I also recommend picking up the Mounting Brackets # C42CR and # C57202 so your wiring connector is readily available next to your hitch receiver. We haven't had a chance to install this hitch on a 2023 Forester as of yet, but when we installed this hitch on a 2022 model we found from the ground to the top inside of the hitch receiver measured 14" which should be similar...

I really like this hitch because the crosstube mounts behind the rear bumper. This leaves only the 2" receiver visible, which not only helps with ground clearance but looks better.

      I do have a solution, but there are no custom fit hitches for a 1990 Toyota Land Cruiser. What you can use is a universal hitch like the Draw-Tite # 41990-07. This is a weld-on hitch so you will need to take it to a certified welder for installation. I know you asked for a Class III but it won't hurt to have the higher hitch capacity since you will be limited by your vehicle capacity. You will also need a universal wiring kit for the 4-way.

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.
