Nicely made, exactly what I want, just wish that the bracket was a little longer, the best place to mount it was on bumper and the plastic trim is on the way to open it but the product is better than expected

So after breaking the plug on my truck I needed a new part and I needed it quickly. I found the complete setup on etrailer.com and it shipped extremely fast. It was also inexpensive! What a find. Now I just have to find the time to install it. Thanks etrailer!!
Comments
I installed the bracketconnector socket on my truck and the installation was a breeze. It actually went easier than expected. The old broken connector popped right off and the new one snapped in place. I had to cut the bent bracket off and drill holes for the screws but the work was minimal. It actually only took about a half hour to complete the job. After destroying the original bracketconnector and thinking I would never be able to fix it I was extremely happy to find this part. Thanks etrailer!

2014 ChevroletSilverado
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.

The 7 way connector on my 2005 F150 was damaged so I replaced it. I wanted to make sure it worked before going to the storage lot to tow my RV. Very pleased with this 7way tester! It worked as advertised!

This kit worked perfectly, it makes a very nice install to add a almost factory trailer tow system and give you the brake controller function!
by: Chris 11/22/2022
It has worked fine for me although I did have water get into the contacts where the vehicle harness plugs in and the trailer brakes became intermittent at times when driving in the rain. I really should have known to seal it better the first time so I took it off and used the stretchy silicone "Rescue Tape" to re-seal the connection. All seems well now. I especially like the convenience of the 7-pin and flat-4 combination.
by: Kevin11/27/2022
The item itself is great. Plug and play, easy and quick install. The problem I had was etrailer failed to include the 4/7-way plug adapter that pops directly in the factory bed cutout (it is a separately packaged item included in this kit). I called them the next morning and they took care of getting it shipped out within the day. Problem is they shipped via usps and took almost one week to get to me. was looking forward to using it within that time frame, instead had to run the cable over my new truck’s tailgate… I believe that if a mistake is made it should be corrected as quickly as possible, not as cheaply as possible.

Plugged right into my 04 GMC Sierra. Two bolts, hook up harness and installed. It came with dielectric grease already on the pins which was great to see.

I 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.
by: Mike 10/22/2022
I got this to replace the factory plug that’s in the rear bumper. Removed the new plug from the angle bracket and is a direct replacement for the factory plug. It has worked great. I think it’s more water tight than the factory plug.
by: Matt02/06/2023
It works well so far. My tech installer was unfamiliar with the design so I suspect he may purchase others. If it lasts 10+ years or more I will be happy.
by: Emanuel02/05/2023
I needed to install it upside down because installing it right-side up would not allow me to put my factory bumper hitch cover back on.
by: David 01/28/2023
Easy installation of this quality product. Nice to not use an adapter for a 4-Pole trailer.
by: Mitch10/13/2022
Works great, I've had it installed for about a year now. I bought to replace some trailer wiring that the previous owner had butchered. It's nice to have both connections in one location even though every trailer I use only has 7 pin connections.

2010 Ford F-150
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.

Quality bracket and ease of mounting with provided tek screws. Although pre-coated, a small package of dielectric grease would make it even better.
by: Franklin12/11/2022
Please provide better hardware to connect to frame. The self tap screws didn't really work and doesn't match the all black trailer frame and tow harness

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!
Comments
Good installation approach for q7’s. Keeps water from collecting in wiring junctions.
Rob - 09/22/2019by: John03/03/2023
Order shipped in a timely fashion. Only complaint is that I wish there was foam sprayed in the box to keep things from shifting. Large hole where the receiver was. All the parts remained in the box though.
Overall VERY happy.

Wiring receptacle still works fine with no problems!
Richard H - 11/06/2022by: Doug10/05/2022
Right out of the package it was easy to install and looks great on my vehicle. Luckily I only needed the 4-pin though as the 7-pin hookup doesn’t function. Would’ve returned it but I needed to use it only a few days after delivery. Gonna just roll with it until I have a need for a 7-pin and maybe try etrailer again (this is the first issue I’ve had with one of their products) or possibly try another retailer.
by: John07/25/2021
The trailer hitch plus 7-4 Pole trailer connector all fit perfect on my 2018 Grand Cherokee. Installed it myself with the help of a couple of jack stands to support the hitch while I bolted it in. Saved a bundle over having the dealership install the Jeep brand. The hitch is barely noticeable. The only issue with a jeep is they do not activate the connector plug so I had to have the dealer activate it after I installed it.
by: Daryl 09/10/2022
Quality product. Plugs worked perfectly with the factory harness. Only down side was that there wasn’t an easy way to mount the bracket to the trailer hitch. I ended up welding it to the hitch.

See what our Experts say about this Hopkins Custom Fit Vehicle Wiring
- Replacement 7-Way Replacement for a 2011 Ford F-150 RaptorWhat you will need is the Hopkins Custom Fit Vehicle Wiring # HM40975. This is confirmed to fit your 2011 Ford F-150 Raptor, and since the connector is not available without the bracket you would just need to discard the bracket or save it as a spare.
view full answer... - Will Hopkins 7- and 4-Pole Trailer Connector Socket # HM40975 Fit 2011 Jeep Grand CherokeeThe Hopkins 7- and 4-Pole Trailer Connector Socket # HM40975 that you referenced uses a standard U.S. Car Connector plug (a round 7-pin plug) to connect to the OEM wiring in your Jeep Grand Cherokee. This part is specified as a replacement part to fit your vehicle if it came with a factory 7-way tow package. You can check the type of connector on your Grand Cherokee to see if it matches this part. I have included a photo of a U.S. car connector plug for your reference. Please note that...

- Replacement 7-Way Recommendation for a 2004 Chevy Silverado 1500Yes, the # HM40975 that you referenced will fit the connector in your picture. The picture is pretty blurry though. So if you are needing to replace that harness as well the part # HM40975-11998 comes with the connector with wires that could get hardwired to the connector in the picture if you were to cut it off.

- Replacement 7-Way Recommendation for a 2002 Chevy SilveradoIt sounds like you have a surge brake trailer that has a 7-way trailer connector on it and need a 7-way to install on your 2002 Chevy Silverado. The part # HM40975-11998 would be the correct harness for you if you had a 7-way on your truck and it (and the harness), got damaged and was in need of replacing. If you only need the connector without the harness you would want the part # HM40975. This would connect to the harness under your rear bumper. Chances are this would be all that you...
view full answer... - Replacement 7-Way and 4-Way Socket for a 2011 Ford F-150Yes, you can use the socket, # HM40975, from the # HM40975-11933 kit as a replacement 7-way and 4-way trailer connector on your 2011 Ford F-150. The plug-in adapter that comes with this kit is only designed for Dodge and Chrysler vehicles, but you can use just the # HM40975 socket as long as your truck came with a factory 7-way trailer connector. I have attached a link to the socket that should save you some money from having to buy the kit that you referenced.
view full answer... - Will Pollak Trailer Connector Socket # HM40975 Fit Factory Tow Package Wiring on 2007 Toyota TundraThe Pollak 7 and 4-Pole Trailer Connector Socket, part # HM40975, is compatible with the OEM wiring harness on your 2007 Toyota Tundra. This socket will plug into the OEM female end socket on the vehicle. If the female socket on your vehicle is damaged or missing I would recommend the Pollak 7 and 4-Pole Trailer Connector Socket with Wiring, part # HM40975-11998. This part is the same connector (# HM40975) with the female socket with pigtail wiring. I am including a link to a video of...
view full answer... - Replacement 7-Way Connector For 2006 Toyota Tacoma With Factory 7-WayWhile we have an option for you to replace the factory 7-way on your 2006 Toyota Tacoma, the Hopkins # HM40975 by itself won't work because the plug on your Tacoma is different. There actually isn't just a plug-in connector so what you would need to do is replace both the plug and lead, which would mean some wiring is needed, so you can use the following: - 7-Pole and 4-Pole Trailer Connector Sockets w/ Mounting Bracket and Wiring # HM40975-11998 So you'd need to cut off your current...
view full answer... - 7-Way/4-Way Kit that Fits 2021 Chevy Silverado 1500Yes the 7-way/4-way kit part # HM40975-11998 does fit your 2021 Chevy Silverado but since your truck already has the round connector that comes with this kit you'd only really need the part # HM40975.
view full answer... - Trailer Wiring Harness that will work for 2016 GMC Savana Van with 6-way connectorIf you have a 6-way on your vehicle, there are two routes you can go. You can add a 6-way plug to your trailer or you can switch out the 6-way to a 4-way or 7-way. I would recommend switching out the 6-way on your vehicle to a 4 and 7-way combo such as # HM40975-11998, so that you have the option to haul trailers with different wiring set ups without having to carry an adapter. I say this because 6-way plugs are not very common. If it is a US car connector that you have installed that...
view full answer... - Do You Have the Bracket Separate From the HM40975 ConnectorI am sorry but at this time we do not sell the bracket separately for the HM40975-11933. We do have the Pollak 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket, part number HM40975, available without the plug adapter wiring.
view full answer... - Replacement 7 and 4-Way Recommendation for 2005 Ford F-250The part # HM40975 normally would plug right in to the 7-way wiring of your 2005 Ford F-250, but if for some reason you have a totally hardwired setup your other solution would be to use the part # HM40975-11998 which would allow you to hardwire the setup to your vehicle wiring.

- 7-Way and 4-Way Recommendation for a 2007 Ford ExpeditionThe only 7-way/4-way we offer that would do what you are looking to do would be the # HM40975-11998 that has a connector that plugs into the back of the 7-way. The benefit to this style of connector is that it if you ever need to replace the 7-way you wouldn't have to rewire the whole thing and you could just replace the connector. If you have the round plug already all you would really need is the part # HM40975 though.
view full answer... - Replacement 7-Way Recommendation for a Vehicle 7-Way that Filled with Water and RustedIf the connector portion of the # HM40975-11998 filled up with water it had to have been due to it getting submerged or being installed in an area that gets direct water sprayed on it when traveling in rain. We have never heard of one filling with water like you described. You would want to either replace the whole thing or just the connectors with part # HM40975. If it's as rusty as you described it would be very difficult to get it all out. But you could try the product called CLR that...
view full answer... - How Does the Hopkins 7-Way part # HM40975 Wire to a VehicleThe part # HM40975 is designed to fit the round 7-way connector that is found on several vehicles. To install it would require your vehicle to have this round connector. (see picture) If instead you needed a way to hardwire in a 7-way to a vehicle you would need the part # HM40975-11998 instead.

- 7-Way Recommendation for 2017 Toyota Tacoma with Capped 7-Way ConnectorIf you have a round plug behind the rear bumper of your 2017 Toyota Tacoma for plugging in a 7-way harness what you would want is the part # HM40975 which will plug right into it. The part # HM40975-11998 includes a harness for hardwiring the harness to the vehicle that would not be needed if you had the connector present already.
view full answer... - Will Hopkins 7-Way and 4-Way part # HM40975-11998 Fit 2017 GMC Sierra 1500Your 2017 GMC Sierra 1500 will work great with the # HM40975-11998 that you have but in reality you only will have to use the 7-way portion of the setup. The # HM40975 portion of the setup is just the 7-way and bracket which will attach directly to the 7-way wiring that your truck already has. There would be no need for hardwiring. Check out the install video I attached for more info as well.
view full answer... - Replacement 7-way Trailer Connector on 2008 Toyota Tacoma With Factory Tow PackageThe Pollak 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket # HM40975 can be mounted onto your 2008 Toyota Tacoma. If the connector on the rear of your truck is still good, and can plug into the new harness, it will work for you. If you need to hardwire in the connector because it is damaged then you can use # HM40975-11998 that includes the same 7- and 4-way with a pigtail harness.
view full answer... - Replacement 7-Way/4-Way Recommendation for 2014 Toyota TacomaThe part # HM40975 is a replacement 7-way and 4-way that will connect to the round connector you have at the rear of your 2014 Toyota Tacoma. If you needed to hardwire the connector as well you would want the part # HM40975-11998 instead.
view full answer... - 7-Way Trailer Wiring Recommendation for 2017 Chevy ColoradoYour 2017 Chevy Colorado might have the round socket already to allow the part # HM40975 to install without needing the wiring harness. But if you did not have the connector the part # HM40975-11998 will fit and work well. Check out the install video I attached for more info on how this installed on a similar 2016 Chevy Colorado.

If you have just bare wires near the spare you'll instead use part # HM40975-11998 which includes the 4-pole/7-way plus a wiring adapter and connector and butt connectors for splicing your truck's wires.

In which case, I wouldn't really be able to know what you have exactly but we do have some possible replacement options. I recommend the 7- and 4-Pole Trailer Connector Socket part # HM40975 or the 7-Pole and 4-Pole Trailer Connector Socket and Wiring part # HM40975-11998.

If the trailer IS connected and you get the E1 code, a probable cause is a dirty trailer connector. Check the trailer connector on the trailer and on the vehicle. Clean out any dirt or corrosion. Corrosion can build up behind the connectors where the wires attach as well. It sounds like the proper voltage is getting at least to the trailer connectors. You can also examine the trailer brake magnets...
