Tow a trailer with either a 7-way or 4-way plug with this dual vehicle-end connector. Included pigtail harness hardwires into your vehicle and the connector end mates with the 7-pole socket to form a weathertight seal.by: WillyGDocVT02/11/2024
Quality is good, but wire colors aren’t standard and there were no instructions in the package for how to wire. I had to google standard pin outs and colors. Pigtail is too short, by about 2 feet and I had to splice twice to make it reach the inside of my vehicle (GMC SAVANA). Once I did all that it worked perfectly but what should have been a 1 hour job turned into an all day project. Do not recommend. Go to your nearest RV store.

The service provided by George and Lacey was the best part of this transaction. Lacey helped me find the right parts and sent me a video about installation. They both worked to correct my order and customized the delivery date.
The parts were precisely what I needed to get power to the bumper for a small trailer and bike rack. A few comments: order more butt connectors as the mfr sent 6 and there were seven wires on my Colorado. When connecting the tail harness to the truck harness, be sure all the wires on each side are the same length. The yellow wire strippers take some getting used to, so practice on several wires first. I’m an ‘average’ handy person so these last two suggestions didn’t come naturally to me, but overall this was a pretty simple installation. When I tested it and all the lights worked, I was a happy camper.

This item came relatively quickly (with a slight delay due to a backorder, but E-Trailer communicated this very well). The directions, the fit and the on-live install video is very helpful. Please watch the video to be sure you are getting the wires crossed correctly - the wire colors from the harness and the factory wires do not all match so be careful there. Highly recommend this product.

2012 Dodge Ram Pickup
This is a fantastic quality part and an excellent alternative to Ford's OE connector (the difference being this one is far less expensive and does not have the Ford emblem. I used the connector to replace the 7-Pin/4-Pin combination plug on my 2002 Ford Super Duty after swapping the bed/bumper/tailgate from a 2012 Super Duty. It is a vastly superior connector in that the 4-Pin is integrally wired with the 7-Pin as opposed to having the 4-Pin spliced into the harness. I would definitely recommend this part for any towing rig. I eve put one on my father's 1995 Dodge Ram 2500. Don't hesitate to order this one!

I have a 2017 SantaFe I have 2 different trailers and need both types of plugs I am using this product along with a curt class III hitch and a curt 56332 wiring harness.
I want the finished outlet to be behind the factory cover I had to modify the Hopkins bracket by bending it in the opposite direction on a angle because the hitch is in the way .a little effort and its great

Easy installation! Kit only supplied 6 connectors when there were 7 wires ...... oops!

Steve, the 6 connectors are correct. The ring connector that attaches to the ground wire is the 7th connector.

I still like the wiring harness I purchased from your company last year. Thank you for asking.

The trailer plug went bad on my 92 F150 several years ago. This plug is the same as my 10 F350. I like the combination 7 spade/4 pin. Other combos have a rubber flap to cover the 4 pin plug. I doubt I’m that disciplined and I would think that rubber cover would dry rot and break off. This plug has spring closure doors and looks great!

This, combined with Item #e45ZR and Item #C68JR, worked great to add both a 4 way and a 7 way harness to my 2021 Kia Telluride. I only used the harness from the Item #C68JR kit, not the socket. I replaced the socket with this item.

The new shoulder connector will fit perfectly. I watched installation videos on you tube and the product I received worked just like the video.

Bought this trailer connector to use instead of the flat 4 wire connector. Wanted a nice finished look on the rear of the vehicle without any hanging wires. Mounts to the Draw Tite mounting bracket without any modification. Only minor problem I had was with the wiring. The wire colors are not the same between the 4 and 7 pole connector. A call to etrailer got the problem resolved. Great customer service!

Great product!
Fits the factory hole in the bumper perfectly.
Attaching the wires was a pain but that was due to GM saving $1 by just cutting the wire ends and not installing a plug......but they were all there so that was a plus.
If you do install this setup AND you install a hitch, leave the spare tire down while you attach the wires. There's plenty of wire with the plug but the factory wires are up kinda close to the underside of the bed so not a lotta room.
ALSO spend the extra couple dollars and get the heat shrink butt connectors, they're available here in whatever size you need.
Another thing to think about, if you plan on eventually installing bed/ cargo lights any time soon, now is the time to add that extra power wire before you crimp, shrink, and tape the hot wire......

Ford F-350 Super Duty
This is a great affordable option to replace your worn out or damaged OEM trailer recepticle. The fit is perfect. It is made by Pollak which is the same as the Ford one you replace. I damaged mine and took the pin connectors out of new housing and installed it on my F350 without splicing wires. Worked perfectly.
by: Jeffrey05/02/2020
I’m glad I chose this over a single plug! No matter what you have on the hitch, you’ll have the plug for it. The pigtail is plenty long enough and the bracket makes for a simple installation. Get some shrink tube or shrink wrap butt connectors as the ones included aren’t going to keep weather out for long.
by: Morris04/16/2020
Perfect connector for what I was looking for on my 2019 RAV4. I originally installed it with the L bracket, but later changed it to be flush in the bumper. Looks very clean. The prefab pigtail made install into the car very easy as well.
by: Craig 02/14/2024
Nice upgrade in place of 4-wire-only. Looks good, works good.
by: Jordan A04/06/2019
This is the same look as a factory install. I was greatly pleased with the overall installation. Super easy to wire up and looks great in the bumper. My truck has the clean factory look for way less than what they had quoted for an install.

2006 GMC Sierra
Only gripe, the plug wiring on the back is at a 45° and the plug in on the front is at a 90°, so dont wire up the wires by the wiring plug but how the plug in on the front would plug in, I made the mistake, but other than that, works great, looks great, fixes botched wiring like my truck had with just twisted together and taped up wires, easy install
by: Brad J05/03/2023
easily connected. liked direct wire system. however lights worked at first, now all are out but brake lights. I think this may be due to the connectors used. havent had time to trouble shoot it yet.
by: Garet02/23/2018
2001 Toyota Tacoma
Bracket is most likely 14 gauge (measured it) and should be easy to weld. Connector appears to be of reasonable quality, but time will tell if it holds up or not. No matter, welding the bracket to my rollpan will be the difficult part, not replacing the connector housing, should it fail. Hard to rate something I haven't used, so first impressions, I guess it's a five star.

When I purchase this wiring and plug kit they said it was for a Chevrolet pickup. I used it on my 1996 Ford f250 only difference is color of wires. easy to figure out. works great and good quality product
by: Thomas 04/08/2023
Same as the trailer receiver easy and simple to install following the installation video. I did use the heat shrink butt connectors as suggested in the video, keeping the connections as much as possible corrosion free.

- Replacement Pigtail for 7-way Trailer Connector on 2015 Audi Q7It sounds as if you need the pigtail that connects to the American spec 7-way, is that correct? If so, you'd need part # PK11998. It's also sold together with the # HM40975 connector as part # HM40975-11998. If you're speaking of the gray retaining clip, it is included with the # PK11998 pigtail, but it's not available as a separately sold item. The product description page for the # PK11998 pigtail provides the wire color coding if you scroll down the page I've linked for you a bit.

- Compatibility of a 7 and 4-Pole Trailer Connector Socket into a 4 foot Pigtail Wiring HarnessYes, the Pollak 7- and 4-pole trailer connector part # HM40975 socket is compatible with the 4 foot pigtail wiring harness part # PK11998. Both parts use a standard round U.S. vehicle connector. In fact, we offer these two parts # HM40975-11998 as a package deal! I added a video for you as well.

If you only need to connect the plug, which is 7- and 4-Pole Trailer Connector Socket # HM40975, that is a direct replacement for many different years, makes and models of Ford trucks with a factory 7-way; for example it is a fit for a 2018 Ford F-150.

You might be best off checking your own manual to verify but here's what I found: In the power distribution box in the engine compartment the trailer lighting fuses and relays are cavities 24, 28, 31, and 39. The fuse for electric trailer brakes is a 30 amp in cavity 18. There are also two fuses labeled "Trailer Tow Module" in cavities 21 and 48. There's also...
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... - 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... - 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 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... - 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... - 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.

- 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.

- Availability of 7-Way and 4-Way with Harness to Run to 2002 GMC Sierra Trailer WiringIf you have loose trailer wiring wires on your 2002 GMC Sierra what you need to install the 7-way and 4-way you mentioned is actually the part # HM40975-11998 which comes with the connector plus a harness with 7-way wiring that you could run to your truck's wiring.

- 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.

If you need the female side connector as well, you would want the # HM40975 if your vehicle has the round 7-way socket already present. If you need to hardwire the 7-way you'd need the part # HM40975-11998 instead.
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... - 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...

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.

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.

- 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.

This socket will plug into the OEM female end socket on the vehicle.

For Hopkins wiring they follow the following wiring scheme: Red = Left turn and stop White = Ground Blue = Electric brakes Green = Right turn and stop Black = Battery Brown = Running lights Yellow = Reverse lights. If you need to add additional wire we do carry jacketed 7 wire by the foot as part # DW04914-1.
