This 7- and 4-pole trailer connector eliminates the need for an adapter and allows you to tow a trailer with either a 7- or 4-pole plug. Socket connects to your vehicle's OEM wiring system and mounts with included bracket.The box arrived opened and damaged. My wiring harness was missing. When I called to tell them my wiring harness was missing they told me that it was shipping separately but could not tell me when it would arrive. I later got an email telling me all of my items were delivered and asked me to leave a review. I still don't have my wiring harness and will not have the hitch installed by this weekend like needed because I don't know if I am ever getting my wiring harness.not to mention the box had no padding around the hitch so it's all scratched up.
Worked exactly how described, great replacement for my risty only bracket and 7 pin connector. Fits my 2006 Chevy Silverado 2500HD perfect, plug and play. Bought specifically because the bracket is included. And with both 4 and 7 pin connectors, I don't have to use an adapter anymore!
I am not sure how this bracket passed quality control. It sure is a good thing I'm not planning on using it. Really disappointing to see how quality is overlooked during the packaging process. This should have never left in this condition.
It was easy to install and took care of the issue I had of one of the trailer light segments not working.
Easy installation and very helpful installation video.
This thing couldn't be better. Easy mounting. Plug and play. I can now connect any trailer I want. Love it, love it, love it!
I bought this because I needed the bracket and it was the quickest way to get it they do not stock the bracket alone. We where installing tommy lifts and needed t move the original connector which was installed on the bumper.
7 and 4-Pole Trailer Connector Socket does not fit my towing vehicle.
Today I just received my etrailer order #114979486, that consisted of: Curt T-Connector Vehicle Wiring Harness with 7-Way Trailer Connector (ITEM # C56431) and 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket - Vehicle End (ITEM # HM40975) for my 2020 Ford Ranger. I easily installed the harness, but the Trailer Connector Socket does not seem to fit on the rear bumper, next to the license plate.
Last week, I chatted with etrailer customer support rep and I was assured that the connector Socket (ITEM # HM40975) would fit on my 2020 Ford Ranger.
This etrailer customer support representative referenced a previous Q&A Topic titled, "Can the HM40975 be used on a 2021 Ford Ranger". I was also assured that 2020 and 2021 Rangers have identically constructed rear bumpers.
Today, I spoke with a different etrailer customer support representative. This rep told me 7-Way Trailer Connector (ITEM # C56431) was not compatible with the 2020 Ford Ranger recommend reaching out to the manufacturer directly for more information.
I'm very frustrated!!!! Can I please get a solution to this issue ASAP.
Here's some snaps of my Hopkins #40975 installation. I can confirm that it's an identical replacement for the 2014 Silverado 1500 trailer-light blank insert, no bracket required. It took me 30 seconds to plug the Silverado's OEM 7-pin round connector (located inside the blank insert) into the #40975 Wiring Kit and snap it into the cutout. Then I tested the flat 4-pin outlet of the #40975 with a 5 dollar 4-pin LED tester from West Marine, and all light functions tested good. Shweet! To remove the OEM blank plug, it helps to reach behind it and pinch the two spring clips holding it in place... same with the #40975 if it needs to be removed for some reason. When I ordered the part from eTrailer, your site had a comment, "This will not fit your vehicle. See below for compatible parts," or words to that effect. Maybe take a look at that and remove the comment, as the #40975 is an exact fit for 2014 Silverado 1500, no bracket needed. Thanks, eTrailer team!
It came with it's own bracket, which is a plus. It was compatible with etrailer.com's part number C56357, which is also a plus. The self tapping screws being the only hardware coming with the item was a disappointment. I just installed etrailer.com's part number 76301 hitch receiver which has a mounting plate for brackets like this. The self tapping screws, which might have been effective, wouldn't have looked "professional." After finding some hardware which worked, it went on smoothly and fits well with the rest of the assembly.
Item received as described. It was simply plug and play. Out with the old, and the new was an exact replacement. Very satisfied.
This dual connector adds a professional looking touch to our tow wiring installation
Scratched my head for a while, trying to find a quality way to connect this vehicle end 4/7 wire socket to my trailer ready (almost) 2015 Audi Q7. Finally decided that it really didn’t need to be bolted, but could be hose clamped to the existing heavy duty Audi bracket.
Mounted it sideways with a 1” diameter and a 3” diameter hose clamp. Be sure to use a 3” clamp with lots of serrations that all it to tighten it down a lot.
You’ll need to drill out the small hole of the supplied bracket to allow a clamp to fit through it. The other hole is a slot, and works unaltered. Small clamp on bottom, large clamp on top.
You’ll also need to relieve a small spot on the trim piece to make room for the 4-wire door to o-en freely. This is marked as red on one of the pictures.
Looks good and should work good!
The self tapping screws that come with the mount are junk,
The product is Good.
Great product, it was just what I was needing to complete my project.
Came in on time. The parts were in good shape and fit perfectly.
Fit and works fine. My old one was just the 4 plug so now I don’t have to use the adapter for 7 prong anymore.
Top quality trailer connector that fir original wiring harness perfectly.
Installed in under 15 minutes.
A very good option to cut down on rattle. This is a durable product that is fairly simple to install. My only complaint is the magnet to keep cover closed when not towing should be stronger. I am happy with the purchase and it looks like it will be useable for years.
This was a drop-in. Literally unplug the wiring harness off the blank, pop out the blank, pop in the new connector assembly then plug the wiring harness back into the connector. Honestly took less than 4-minutes. Awesome product. My local hitch install company wanted $150 just for the install of the connector.
Fast shipping. Nice quality product
Great product at a great price. It was an exact fit and looks great. I like having the ability to plug in my 7-prong plug on my travel trailer or the 4-pin plug on my boat, without needing an adaptor. Got super fast shipping too. Buying from etrailer.com was a win- win-win.
Super fast shipping easy installation looks better than factory plug love the 7way and 4 way so no more dealing with adapters
nice looking product, haven't plugged into it yet to know of the electrical part, caution about the install, make sure you have about 5" clear directly behind the install location of your bracket to allow room for the connector and to attach your vehicle plug, see photo, I had wanted to mount this on the bottom of my bumper, but not enough clearance
I’ve had a great experience with the etrailer company. I fully equipped my 2022 Toyota Highlander which did not come with the factory tow package. I bought the receiver hitch, the wiring harness kit, a brake controller plus this special 7x4 pole connector, which did not come with the wiring harness, which only had.7 pole. I also bought a special bracket to mount the connector where it needed to go. Their service was great. Unfortunately they did not carry the Anderson weight distribution chain type hitch that I purchased from Anderson. They are a well run, customer focused Company that I highly recommend

Top quality trailer hitch at a very reasonable price!
Chevy 2500 HD 2005 Duramax
Installation was very easy and only took about 15 minutes to hook up and secure wiring on truck.
Yup. Still works after a year in operation. The only thing I am unhappy with is my vehicle thinks there is always a trailer connected and the backup sensors and side sensors are automatically disabled.
This product was exactly what was portrayed on line. Wiring harness was very simple to install and works extremely well.
When I finally installed it about 3 months ago, the plug in connectors did not match what I had on my truck. I ended up just cutting them off and splicing them into the connector from my truck
Exactly as described. Fit perfectly into my 2014 Silverado bumper outlet.
I installed my Curt T-Connector today to my 2018 RAM 1500 Sport 4x4 Crew Cab. The mileage on the truck is at 10679km's. Although warned that the spare tire might require removal (via web site info from fellow RAM owners) that was not the case as there was enough room to remove the OEM connector (which is the short end of the assembly) from the factory housing. The actual disconnect and re-connect took only a couple minutes. I spent a about 15 or 20min's trying different wiring run routings for the aux. four connector plug wiring run. Some tie-wraps where installed to snug things up out of the way and I was done. I also dosed the connections with a shot of Krown 77 lube/rust inhibitor. I'm in the "Great White North" so salt use on roads is a given during the winter months. A quick test run of the lights and I was done. The build quality of the T-Connector is very good..equal to OEM or better I'd say.
Easy plug and play simple installation.
Fast delivery, and easy to find products. Second trailer hitch I bought from e-trailer. Great products
Awesome!! I bought an OPT7 triple LED light bar for my Chevy Colorado and I didn’t want to splice wires or lose a whole lot of time trying to figure out how to wire it up so I googled and I came across a gentleman who used this product and Im very thankful for this connection and my light bar works smoothly and I have full use of the reverse camera AND I don’t have any wire mess outside or underneath my truck! Easy to install, my first time doing this and it literally took me about 2 minutes, if that! Definitely would recommend this product to anyone with a truck!! Thank you guys!!
Was exactly as stated in description. Just unplugged old plug and plugged in new one. I had two plugs to replace and added an extra "T" plug for another 4 prong. It only took less than 15 minutes to install all 3. Customer service is wonderful. Everything I have bought from ETrailer is top notch and delivered on time or earlier.
Order class iii hitch and wiring harness for my 13 keep grand Cherokee . Came next day. Installed in 20 minutes. Great product. High quality and easy install
Product was shrink wrapped, taped and boxed ver professionally. Website also very easy to use
Would definitely recommend to anyone
This is a great vehicle to trailer wiring harness just plug it in and you're ready to go and that's all they are to it plug and go and I recommend it.
This T-Connector is working great. Installation was simple. It was truly plug n play.
I used it to connect a LED light bar on back of truck; allowed me to install the light without using the existing trailer connector, so it is still available.
Easy to install works great shipping and communications was fantastic. Now my USMC LED light hitch cover is on the truck without an adapter.
Easy instructions, installation was a breeze. Very important to torque bolts down to spec. Also will need to have dealer “flash” vehicle to activate trailer lights. 5 stars
Perfect fit. Took 20 minutes to install wire harness and hitch receiver.
Unfortunately, the product ordered did not fit my application and I will be returning!
Arrived on time and just what I need.
You sent me the wrong wiring kit. It doesnt work on my vehicle.
Did not match my plug into car. So could not use and returned.
This is such a better way to install a tail light bar. No cutting or splicing wires! FABULOUS!
Easy to install and tucks away nicely next to the hitch. No hanging wires and really clean look
Took less then 5 min to install, solved the hassle of going to a brand name shop and paying 5 to 6 times to have them install. Plan on towing a utility trailer my wife and I do a lot of antique shopping. Will tell all my friends, great product
