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.This was a great addition to the hitch I bought for my 2011 Grand Cherokee. I was able to plug it right into the factory harness for a perfect fit. The only issue you may have is the trailer lights won't work until you get the computer flashed from the dealer to tell the Jeep it has a towing harness attached now. 54337
Thanks for the info. We have seen some dealers so it for less even for no charge. Just depends on the dealer.

Good quality no issues 568536
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. 538985
Matt W - 07/07/2019Good fit and worked just fine. A bonus is that it also has the 4-pin connector built-in so no adapter is required for that kind of trailer connector. 563271
Plug and play, couldn't be easier! Decent price too. Only 4 stars due to the ridiculous self-taping screws they expect you to put through 3/16" steel (just guessing on the thickness - it's 1/8-3/16 best guess...). The install video on the site shows them using nuts/bolts/lockwashers to install it, which is what I did. This product should come with that arrangement instead of the self-taping screws, in my not-so-humble-home-installer-opinion... 554683
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! 567819
Rob - 09/22/2019very easy to install. it is a rather tight fit on a Chevy traverse. Allows a factory install of aftermarket hitch by using GM harness # 25910884 ($68.00) . Harness comes with snap in wire ties that go in holes on cross frame of rear bumper. Vehicle to connector harness is located to the rear of right rear tire between outer body panel and tail light . Use flash light and look up. Cord fits E trailer Vehicle end plug 40975. Need to drill two holes in cross frame for bracket. It all snaps together very well. Also need to add 3 relays in engine fuse box. GM13502753. This is gray relay 1/2 in square and has 2750 market on top. this eliminates splicing delicate factory wiried and hassel of hot wire from battery. Bumper skirt snaps back into place and hides hitch totally on 2013 Chevy Traverse. 87284
Chas - 07/03/2014This was what I needed to make my new truck able to pull my two trailers. You even had a video showing how to install it on your web site, this helps a lot. Thanks for the help. 211204
Dan R - 08/05/2016I just received my package from Etrailer.com and it was nice to open the box and have the right part/part I ordered arrive. Opened up the box staged my parts and started the install. It was very easy with the instructions that were sent and the video on their site that anyone can do this install with no issues. Hitch was on in no less than 15 mins from opening of the box to final torquing of the bolts. The customer service at this company is top notch. I have never had anyone from a company email me before after ordering from them like I did with this company and in business today you are seeing less and less of this type of customer care and service. AWESOME job Guys and Gals I will buy all my accessories from here. 90754
This is a plug-in replacement for my 2010 Ford F-150 with factory installed trailer package. I had this exact same connector but someone unclipped it and stole it. Ford Parts wanted over $100 for a replacemnt (they included the entire rear bumper harness that I did not need). I had the cutout on the hitch that exactly matched this bracket and the blue socket that you see in the optional pigtail available for this product (see attached photo). I snapped this dual connector into my existing cutout - fit perfectly. Did not need to use the included bracket. So if your factory connector is damaged or stolen, use this as a snap-in replacement. The only difference is it says "Pollack" instead of "Ford". I called Hopkins before I bought and they said they supplied a lot of the OE parts Ford uses. 55449
I ordered DrawTite hitch #76031 along with Tekonsha Wiring #118273 and HM40975, 7 and 4-Pole Trailer Connector Socket for my 2018 Nissan Pathfinder SL. I ordered on a Thursday afternoon and the merchandise arrived the following Monday evening (with free shipping and no tax). The hitch arrived in excellent condition with no scratches or scrapes and was packaged very well. The total for my order was a great price! This also included a tube of dielectric grease and a brush. To get a factory hitch would have required an expensive "Technology Package" at a cost of over $2000 or a dealer install which would have cost over $1000. I did the install of the hitch myself. It would have been far easier if I had a lift to raise the vehicle off the ground, and a helper to hold the hitch in place and get the 6 frame bolts started. I used an ice chest to prop up one side of the hitch while I got the bolts started on the other side. Watch the videos from etrailer before doing the install. I did have to trim about one-eighth of an inch off the corner of the gasoline vapor recovery box on the left underside of the vehicle to get the hitch into a position so that the holes in the hitch lined up with the weld nuts on the frame. I used a rotary file on the end of my drill to do this. The 2X2 receiver does barely touch the bottom of the rear trim on my Pathfinder but did not require cutting the trim to get it to fit. The Tekonsha #118273 Factory Wiring was not difficult to install. The etrailer video on how to install this item was not as good as it could have been. The installer says he is going to make the 2 vehicle connections inside the left-rear of the vehicle "by feel," which may be fine for someone who knows what he is doing, but was not helpful to me. I pulled back the trim on the inside left rear to make these 2 connections. You should definitely make ALL of your wiring connections BEFORE installing the hitch itself. If you don't, it will be very difficult to reach the connectors outside the right rear of the vehicle if the hitch is already in place. BE WARNED about this. The HM40975 connector was very easy to install and by having it you will not need to use an adapter to use a 4-way flat trailer connector. I used 2 stainless steel bolts to fasten the bracket into place instead of the included self-tapping bolts that were in the kit. This item is well worth the small cost. I am completely satisfied with my purchase from etrailer and will not hesitate to recommend them highly. Both George and Adam at Etrailer were very helpful. See the picture of the completed install on my 2018 Nissan Pathfinder SL. 566326
Trailer plug unit (Pollack 7 & 4 pole for my F-250 was broken by the car wash. Called the dealer and they wanted double what e-trailer sales it for plus I had to special order and that took too long to ship as I needed it immediately. I went online and found ETrailer.com and they had the exact replacement device that was identical to what the manufacturer had installed. I ordered it and asked to have it within a set timeframe and e-trailer did exactly what they said they would do! The lady I spoke with Cathy was on the stick with the entire order and follow-up. The Etrailer staff then followed up the very next day of delivery. I have just installed the plug this morning so it has to be tested but do not forsee any issues as it is the exact replacement which worked great before. I am very impressed with the service here and will most definitely buy from them again as well as refer my freinds and business associates. I manage a commercial fleet as well as work with many other contractors who have trucks and trailers and there is always the need for something in this category. Great job ETrailer, you have a new long term customer. 42962

Zachary G - 03/12/2017The 2018 GMC Sierra 1500 base model with no options has the wiring harness at the bumper. The bracket and bolts are not needed on the GMC 1500. 552385
Was exactly what I looked at on-line. The description was spot on. Was shipped in a timely mannet and it installed in just a few minutes 225112
Marshall a - 09/11/2016Quality OEM [email protected] substantially lower cost then OEM. 83070
David S - 06/03/2014We hope the rubber coating takes care of the problem. If not, we've got a couple of suggestions. You mentioned dielectric grease. If you weren't already, you can be pretty liberal with the application. You can fill the socket and push the connector in and wipe the excess that squirts out. If all the voids are full of grease, there's no place for the water to go. Second, on most of these types of connectors, there is a rubber gasket on the vehicle side that usually stays in, but will sometimes pull out when you remove the cap or the previous 7-way connector. If you still have the cap or old connectory, you may want to check for the gasket.
-- Patrick B - 6/9/2014Here'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! 120915
Ron P - 03/19/2015Great 904383
Paula from CS is Top Notch Install was Very Easy (I used OE location rather than the Supplied Bracket) Saved big $$ over OE 903439
Bracket rusts badly connector works well 903294
2016 enclave, will need to make the elongated hole longer to fit the holes in the hitch mounting tab. you can flip the bracket around, but it put the end close to the tire. If you want to use the fascia cover you will need to trim the cove where the plug hits, about 1inch slot from the edge. 899534
