Once installation is complete, the 4-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.

This was my first time pulling my 20 foot CC boat and brand new trailer with my 07 Trailblazer which came with the factory installed tow package including the factory installed 7 pin connector for the lights. I ordered the wiring connector item as it had a guaranteed fit for my truck. I went to install it and initially thought it did not fit correctly as I was trying to attach it by flipping up the pin connector cover underneath the rear of my truck and putting it in there, this was wrong but I did not know it....briefly went and reviewed my truck manual but it did not go into any detail on how to connect the trailer wiring, went online and finally found out that I needed to reach behind the cover piece and squeeze in 2 tabs to release the tow truck wiring connector, this is what the Hopkins harness is designed to fit into and it worked perfectly. As I just did this I have no idea what the longevity of the wiring harness will be but it does come with a nifty little cover to protect the electrical pins. As I do not plan on using it that often I removed the harness to keep it safe and sound.

I store the device inside my truck and do not leave it attached to save it from the elements, so far one year later works perfect.



by:

Hitch is on! Piece of cake to install, everything lined up perfectly. I ordered wiring for my car according to my cars build sheet stating that it was pre wired for a tow package but I'm unable to locate any type of plug in so I'll need to return the one I ordered and get the other type. Please advise me the best way to do that.

Perfect fit for my 2005 GMC Sierra! The 6 narrow pin male plug fit perfect into my 7 narrow pin receptacle on my truck. It gave me parking lights, brake and my individual turn signal lights all from the four pin trailer plug. Beware of internet re-sellers that say their #41155 will work if they are showing you 6 wide male pins that will not work. etrailer is the best! Super fast shipping, fantastic customer service and all at a great price! Thank you!

Just what I needed..came in early than planned and fit right..thanks

Worked as it should. Only used with a small trailer. Good product as always with etrailer. If not good, they make it right.



by:

product functioned as expected...... the round plug that fit the tow vehicle needed some slight modification.... after i year the grounding pin on the flat four plug fell out,.... simple enough fix....... still works great.

Thank you for leaving a review! The product page does say all you have to do is plug it in if you want a 4-pole connector. Which is true, you can just tuck those red and blue wires away unless you need the braking and an auxiliary power wire. It sounds like your trailer just has a 4-pole flat for trailer lights so you do not really need those 2 extra wires if that is the case.



by:
2014 Dodge Durango

The trailer wire harness for my 2014 Dodge Durango worked perfectly. It fitted into the prewired factory wire harness attached behind the bumper. I had to have the dealer program the vehicle for the lights to work. The dealer did not charge me for this service, since I was having some other work done on the vehicle they did it as a courtesy. Normally it cost about $50 to do the programming.



by:
2015 Ram 1500

Customer Service Reps kept me informed about the status of my order. The delay was because the manufacturer was slow in shipping to etrailer.com. Once received, I was immediately notified that the item was on the way. I can always find what I need at etrailer.com, the price is great, and the service is superb. Thanks guys for always being there to help me with my needs. Keep up the GOOD work!

Ordered the Hopkins plug-in simple wiring kit with 4 pole connector (41155) for my 05 Nissan Titan. Received what I order very quick. Connected perfectly to my truck with out any issues. I was ready to attach my trailer and go fishing. It was exactly what I ordered.

The reason for three stars is that you'll need a relay tow package kit in order for it to work . It should come with the 4 flat plug for the trailer lights to work . Other that that simple plug & play done

4 stars is for quick delivery and easy ordering, I have not used the extension yet. But, thanks for everything that went so well so far.

Everything fit perfectly, the videos are excellent and the staff is knowledgeable,and patient with us do it ourselve customers.
Pricing is fair, so they deserve 5 Star rating.

Quick delivery and product seems good. Connection to my Audi is not perfect, there is no snap lock on connection. Taped it together with electrical tape.



by:

Plug in and works great. Took off the old plug that was all green with crud. Fit my truck just as ordered. All trailer lights work as suppose to.



by:
Jeep Grand Cherokee

Quick delivery and easy install. Didn't work and found out that if the towing package didn't come on the Grand Cherokee, you have to go to the dealership and have it programmed or "turned on" in order for it to work. No fault of etailer.



by:

THE HITCH FITMENT WAS PERFECT. THE WIRING HARNESS WENT TOGETHER EASILY. GREAT PRODUCTS, PACKAGED AND SHIPPED FAST.

I MAY PURCHASE ONE FOR MY VAN.

THANKS.

  • 4-Way Replacement for 2014 Audi Q7 with 7-Way
    Since your 2014 Audi Q7 had a factory 7-way you could replace it with the part # 41155 and you'd have a 4-way in place of the 7-way.

    While we don't have an install video for the # 41155 that you referenced I did attach an install video for a similar product that installs the same way on a very similar 2014 Chevy Silverado as your 2015 model.

  • Availability of 7-way to 4-way Adapter For 2010 Porsche Cayenne to Power Curt LED Indicator Lights
    It sounds like you already have an existing 7-way connection on your 2010 Porsche Cayenne and would like to use a 4-way adapter to connect to the Curt Auxiliary LED Indicator Lights # C53201. Since the # 41155 is not a confirmed fit for your vehicle you will not be able to use it. Instead, I recommend using the 7-Way to 5-Way/4-Way Trailer Adapter for Vehicles with Lamp-Out Sensors Towing Trailers with LEDs # C35FR. This will plug into your existing 7-way and allow you to use a 4-way...

    The 2014 Chevrolet Express Van if equipped with the factory tow package would have come with a US-Car connector which you can see in the attached video at about the 1:30 mark. In order to use this US-Car connector you will need an adapter to go from this to the end of the bumper, the Hopkins Plug-In Simple Wiring Harness part # 41155 for a 4-way or the 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket part # HM40975 for a 7-way.

  • Will Light-Up Rectangular Trailer Hitch Receiver Cover Fit a 2010 Lincoln Navigator
    As long as your 2010 Lincoln Navigator has a 2" hitch receiver the Flint Hill Goods Square LED Brake Light Hitch Cover # FHG72VR will fit. If you don't already have a 4-Way flat connector (or yours is damaged) then you also need the Hopkins 4-Way Wiring # HM11140495 if you don't have the factory tow package or you need the Hopkins # 41155 if you do have the factory tow package. Attached are some review videos for you to check out.

  • Adding a 4-Pole Harness to a 2013 Audi Q7 with a Factory 7-Way
    It sounds like you're trying to install a standard 4-pole on your vehicle. To add a 4-pole to the factory 7-way on your 2013 Audi Q7, you can use the Hopkins Plug-In Simple Wiring Harness, part # 41155. This will connect into your 7-way and give you the 4-pole you need. I've linked to a video installation of this harness on a 2018 Dodge Durango so you can see how it works. However, if you have a 4-way round on your trailer, then you can use two adapters to get it to hook up to your 7-way...

  • 2014 Audi Q5 Trailer Wiring Recommendation
    The # 41155 is designed to replace a trailer 7-way and provide a 4-way connector. Sounds like you do not have any trailer wiring so this product wouldn't be the correct wiring kit. The only solution we would have would then be a universal wiring kit like the part # 119250KIT.

  • Easy Way to Add 4-Way Trailer Connector to Rear of 2014 Volkswagen Touraeg with Round Connector
    Thanks for the picture of the trailer wiring connector you have on your 2014 Volkswagen Touraeg, based on that your vehicle is wired for a 7-way and just missing the socket. So the easiest solution to give you a 4-way is the part # HM40975 that you referenced. This has a 4-way on one side and a 7-way on the other plus comes with a bracket to mount easily to your rear bumper as well.

  • Where is 7-Way Harness on Vehicle for Install of Hopkins 4-Way Adapter
    If your 2014 Audi Q5 has factory 7-way wiring like what the Hopkins kit part # 41155 is designed to fit it would be somewhere behind the rear bumper. It wouldn't be anywhere else as the connector would need to easily mate up to a 7-way that would end up mounted at the very back of the vehicle.

  • Trailer Connector Location for 2013 Express with Factory Wiring
    If you had a factory connector it would be located at the exterior rear of your vehicle under the bumper most likely on the drivers side. If you have that plug you will need the Hopkins Connector # 41155. If you do not have that plug you would need to run your 4-way from the taillights with the Tow Ready # 118392 wiring harness. I have linked all the wiring harnesses for your specific vehicle for you convenience.

    When installing the Tekonsha Vehicle Wiring Kit # 119250KIT on your 2014 Audi Q7 the harness wires will clamp directly to the appropriate circuit wires on the vehicle without splicing into the wire. You won't be able to attach or connect to the plug itself that you referenced. You did reference in your question though that your Audi is equipped with trailer pre-wiring. If this is the case then there should be a round factory plug located behind the rear bumper. If this is present then...

  • Complete Towing Setup for 2011 Chevy Express Van
    I can help you find everything you need. Assuming that this is the passenger/cargo version and not the cutaway cab and chassis, for a hitch I recommend going with the Curt Class V Hitch # C15320 . This is a 2" receiver hitch and is the highest rated hitch for your vehicle in terms of towing capacity- which will come in handy if you have the 3500 Express Van. If you've got the 1500 Express or 2500 Express, you'll still be limited to the factory recommended towing capacities for those models...

  • Installing the Rampage Light bar on a 2020 Ram 1500
    The Rampage # RA960137 Tailgate Light Bar you referenced is NOT a fit for your 2020 Ram 1500. However, the Rampage # RA960134 IS a confirmed fit for your Ram. The light bar plugs into your 4-pole trailer lighting connector. If your truck does not have this connector you can install the Hopkins # 41155 Simple Wiring Harness. I have included links to these product pages and a review video.

    For your 2013 Chevy Express 3500 I can't tell if you have a factory tow package or not. The trailer button on the dash unfortunately isn't a give away. If you look under your vehicle in the rear, you will be able to determine if you have the round factory wiring connector. This is found in the driver's side frame rail. I've attached a video of the 4-way plug # 41155 to assist. If that plug isn't present then you will simply use the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer...

    The Hopkins Plug-In Simple Wiring Harness 4-Pole Flat Trailer Connector # 41155 has a bracket designed perfectly for it: the Hopkins Fold-Over Mounting Bracket # HM48595. I attached a video that shows how to use it with your 4-pole flat harness. It just folds over the harness and can be screwed up into your bumper, hitch, etc. Some also use separate no-drill mounts like the #18136 long bracket or # 18140 short bracket. These are separate mounts for your bracket mount if you don't want...

    If your 2017 Grand Cherokee has the factory tow package with the 7-way trailer connector also known as the US CAR connector located behind the drivers side of the rear bumper as shown in the provided photo, the Hopkins # 41155 will work. This being said, I'd recommend going another route. If you used the # HM40975, you'd have both the 4-pole and the 7-way trailer connector. If the hitch you're using already has the trailer connector mount on it, the # HM40975 would attach right to it, otherwise...

To complete your towing package, you can use ball mount # 3594 with 1-7/8 inch ball # 19256 or 2 inch ball # 19258. For trailer wiring, you can use Tekonsha harness # 118470 to add a 4-Way flat connector to the rear of the vehicle.

  • 4-Way Trailer Wiring Harness Recommendation for 2015 Chevy Silverado 1500
    There should be a round connector under the rear bumper of your 2015 Chevy Silverado that would allow the 4-way harness part # 41155 to connect to. If not, you would need to hardwire a universal 4-way kit like the part # 119250KIT to your truck taillights.
