I sent an email to verify the correct trailer plug for my Sub and they responded in a timely manner. Made the purchase and it fit perfectly!

Just what we were looking for! The 2007 Chevy truck needed a replacement connector and this did the job!
by: Herb H.11/08/2023
I twisted this connector into the stock location and the locking tab that keeps it from twisting back out broke off. I locked it into place with a screw so it won’t twist out. Disappointed that it broke so easily .

Broke my trailer electrical socket on my GMC pickup, I’m 1,500 miles from home waiting for the snow to start melting to go home. The local GM dealer wanted over $70.00 for replacement part. Found this one at etrailer.com for $16.95. I had it sent priority mail as mail has been slow here in AZ , received in six day and took less than five minutes to install. Hate to leave AZ , but home in SD is calling. We will be be back next winter. Thanks to etrailer for saveing me money I’ll need for gas home.

Very easy...Installed in about 10 seconds. Product did not completely cover the holes through the bumper that existed from the factory harness insert. So you can see light a little bit of light around the product.

This connector arrived fast and was very easy to install. Took about two minutes to put in. It seems to be of very good quality.

Perfect fit for my 2008 Silverado. Identical to the adapter used in my wife's 2007 Suburban, except hers says "GM" and mine says "Pollack." This is all assuming it works, I haven't hooked a trailer up to it yet.
by: Matt Q09/06/2023
Fast shipping, superior product, I would definitely buy again!
by: Leon07/16/2013
Looks to be good quality. Easy to install.
Remove the old connector by depressing the keeper, turning it counter clock wise about a quarter turn, slide it out, depress the keeper on the wiring harness connector and unpluging the unit. Install the new connector by pluging in the wiring harness connector, sliding the unit through the bumper hole and turning it about a quarter turn clock wise to lock it in place. It took less time than writing this.

2007 Chevrolet Silverado 2500
Old electric plug in on my 2007 Chevy 2500 was worn out. Cord from RV would not stay plugged in. Went on line on E-Trailer, ordered a new part for GM vehicles, when it arrived, it took me about five minutes or lees to remove the plug all I needed was a small regular blade screwdriver. New part woks fine. This is the 2nd or 3rd time I have ordered from E-Trailer. I have always been satisfied. Thank you Ken Hill

Fit no issues tight and quality. Spot on. 2011 gmc 2500hd fit right in the factory light plug in. Those that don’t have the 7 way connector already in it this adapts.

Replaces plug with broken cover tab. Old plug matches photo. Correct model year replacement not exact duplicate but fits cutout and wire harness. Average price. Very fair shipping fee.

by: Joel 08/27/2018
After 18 years, my original trailer plug connector was showing signs of corrosion. When I bought a travel trailer with electric brakes, I knew I could no longer trust my old connector. I purchased this replacement because it is identical to the OEM connector which I knew was excellent quality, not a cheap knock-off. It was simple to install and the wire connector plugged right in. I've been using it extensively for a year now and it's been working flawlessly. I'm glad I purchased this quality connector that I can trust.

works well, no problems, fast delivery
by: Henry S.05/05/2014
After spending a little time online figuring out how this connector attaches to the factory hitch (push the tab, twist about 1/4 turn, pull out far enough to reach wiring harness connector), I ordered one from etrailer. When I got it, it took me all of 5 minutes to remove the broken connector and install the new one. Upon examining the OEM connector, which says "GM" on the lid's outside, it says "Pollak" on the inside, so the OEM part was built by this aftermarket company. No wonder it fit so well! BTW, the original broke because of cockpit error, not because of manufacturing defect.

This little marvel was a piece o' cake to install. Less than 10 minutes from taking it out of the box to installing in the bumper of my Chevy and wiping my hands on my pants. If my nosy and talkative neighbor wouldn't have been staring over my shoulder, it would have been installed in under 5 minutes.

2012 Chevrolet Silverado
Looks like OEM and took all of a minute or two to install. The video was very helpful to show how to remove plate on back of rear bumper. The wiring harness on my 2012 Silverado wasn place so it was only a matter of removing plate and plugging in. A seven point adapter then plugs into this and the trailer plug just pushes onto the adapter. I tried both a seven point adapter that I kept from my 2005 Silverado and also a seven point adapter that my brother has on a 2011 Honda Pilot and they are all universal and worked just fine.. Very user friendly.The tow hitch took about 45 minutes to also install with no help (though a second person could make it a 30 minute ordeal tops). Very pleased and the shipping was ahead of original date with just normal ground freight..

2007 GMC Sierra Classic
Exact fit and works great. I couldn't give it a 5 because it rotates slightly in the mount which doesn't seem to affect it's function, but the old factory part that it replaced didn't do that.

used this plug to replace the factory "filler". this item is well built, excellent spring, just what i needed to keep the 7 way option (used with a four way trailer harness). breeze to install and fits snugger than the factory one (2008 silverado). would recommend and first time ordering with etrailer...will do business again, great products to fit any situation, outstanding service and prices. videos are great too. look no further than this company. shipping was fast. A++++ all the way around. good job guys.

REPLACED OEM PART PERFECTLY. TWISTED OUT THE OLD ONE AND REPLACED IT WITH THE NEW ONE, PLUGGED IN THE HARNESS AND WAS GOOD TO GO.

2004 Nissan Titan
The manufacturer (Pollak) directed me to etrailer where I easily located the correct trailer connector. Apparently my 2004 Nissan
Titan was retrofitted at the dealer with this style connector. I bought the vehicle new. The dealer's parts department had no information for this part or the hitch.
Your website was easy to navigate and the pictures simplified the process. Replacing the broken original was a five minute job. The new connector fit perfectly. I wish all repairs were as easy.

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.

by: 2006 Silverado 2500HD08/03/2023
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!
by: Jason06/24/2023
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.

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.

I am sorry that this has been a frustrating experience, however I do have an answer for you. The Hopkins connector part # HM40975 is technically not a fit on its own for a 2020 Ford Ranger. The short reason why is that the Ford Rangers do not have the round US Carr type of connector to plug into. Now by adding the Curt harness part # C56431 like you did, does make that round connector that you can plug into the back of the Hopkins connector that will give you the 7 and 4 way you want. Since it is using two different manufacturer products together, I do encourage you to test the 4 and 7 way to make sure all the signals are working correctly. In theory they work together, however they are not tested. The issue is going to be that the bracket that comes with the Hopkins connector is not going to match with anything on the Ford Ranger to connect to. It would just be bolted to the bumper or you could also consider using part # C57202 to install it on your hitch.

2014 Chevrolet Silverado
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!

Although I havent towed since installing the Hopkins Pollak wiring kit since I installed it a year ago, I have tested the 4-pin connector for proper function using a 4-pin LED tester from West Marine and it checks out okay. Recently I inspected the kit for water intrusion mentioned by one of the raters, and I found no evidence of moisture inside the dual-connector compartment. On installation, I did make liberal use of the dielectric grease that accompanies the kit. Good product, easy installation, and great price.

2017 Nissan Pathfinder
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.

2015 Audi Q7
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!

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.

Toyota Highlander
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

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.

- Comparing Hopkins and Pollak 4 and 7-Way Trailer Connectors
- In regards to Pollak and Hopkins, they are both great options. That said, if OEM parts give you any indication of quality then Pollak would be the better choice as they are the OEM for most manufacturer in regards to trailer connectors. Personally, I've had less issues with plug fitment when using the Pollak brand.
If you're looking for both a 4 and 7-way connector, I recommend the 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket part # HM40975 which also comes with a mounting...
