Fit perfectly the whole hitch and wiring install was a breeze.
by: Tim07/04/2023
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.

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.

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!

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!

Items worked as expected, needed some assistance with harness but satisfied overall
by: Torsten03/06/2017
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.

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.

Told me all I had to do is plug it. Now I have to wire tge blue and red cable. My vehicle comes with the the 7 plug tow package. Was told to turn it into 4 plug all I had to do is plug it.

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.

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
by: Gary 07/15/2021
I have bought three different trailer hitches, wiring and other items.
Everything fit perfectly, the videos are excellent and the staff is knowledgeable,and patient with us do it ourselve customers.

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.

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: Steve H.04/10/2014
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.

- 4-Way Trailer Connector to Plug in to OEM Tow Package Wiring HarnessFor a 4-way trailer connector that plugs directly into the factory round tow package connector we have Hopkins # 41155. I've linked a video review for you to take a look at.
view full answer... - Does Hopkins 4-Flat 41155 Fit 2002 GMC Envoy With Factory 7-WayIf your 2002 GMC Envoy has the factory 7-way, which is what I think you were referring to by "7 wire cone toe", then it has the factory tow package and yes, you can replace it with the Hopkins Plug-In Simple Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector # 41155. I have added a link below to a video review for you to check out as well if you'd like of the Hopkins # 41155.
view full answer... - Where is 7-Way Harness on Vehicle for Install of Hopkins 4-Way AdapterIf 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.
view full answer... - 4-Way Replacement for 2014 Audi Q7 with 7-WaySince 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.
view full answer... - Recommended Trailer Wiring Harness for 2012 Audi Q7 with Tow PackageTo install a fully functional 4-Pole flat connector to connect with and activate the signal lights on the trailer, I recommend the Hopkins Plug-In Simple Wiring Harness # 41155. This is confirmed to fit your 2012 Audi Q7 with the factory tow package and will install by plugging directly into the OEM tow package wiring harness. No cutting or splicing is required. I have attached the installation details for you to check out.
view full answer... - Will 7-Way to 4-Way Adapter 41155 Work Well on 2014 Audi Q7The 7-way to 4-way adapter part # 41155 that you referenced will work great on your 2014 Audi Q7. All of the lighting functions will work.
view full answer... - How Does Hopkins Plug-In Simple Wiring Kit with 4-Pole Connector Install on a 2015 Chevy SilveradoWhile 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.
view full answer... - Trailer Wiring Harness for 2013 Toyota RAV4For your 2013 Toyota RAV4 the trailer wiring harness I recommend is the Tekonsha part # 118578 as it's the easiest to install and is the most reliable. I attached an install video for this for you to check out as well.
view full answer... - 5-Way For 2001 Chevy Tahoe With Factory Tow PacakgeThere are just a couple of parts you'll need to add a 5-flat to your 2001 Chevy Tahoe with the factory tow package. First you'll need to add a 4-flat, then you'll need to add an adapter to turn it into a 5-flat, which you can do with the following parts: - Hopkins Plug-In Simple Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector # 41155 - Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter # 20036
view full answer... - Trailer Connector on 2008 Chevy Silverado 1500 not Working ProperlyYes there is such a thing as a connector going bad on either the tow vehicle, like your 2008 Chevrolet Silverado 1500, or the trailer. This can be the result of corrosion build-up, which can be cleaned, or damaged wires. You can also check to see if any fuses might need to be replaced. If there is corrosion build-up then you can try cleaning it first and if that doesn't work then you will need to get a new connector for your truck, If you just have a 4-Pole you can use the Hopkins # 41155,...
view full answer... - 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.
view full answer... - Does Computer have to be Reprogrammed to Install a Trailer Wiring Harness in a 2017 Toyota 4RunnerIf your 2017 Toyota 4Runner SR5 came with a factory installed 7-Way trailer connector then yes, Hopkins Plug-In Simple Wiring Harness # 41155 will fit. The vehicle would not have to be reprogrammed. If your 4Runner did not come with a trailer connector at all then you would need to hardwire one in using # C59496. You also would not have to have the computer reprogrammed when installing this harness.
view full answer... - Will Hopkins Plug-In Trailer Wiring Harness 41155 Fit a 2014 Audi Q5 QuattroHopkins does indeed list wiring harness # 41155 as a fit for your 2014 Audi Q5 as long as it came with the factory tow package. If your Q5 does not have the factory tow package then you would use harness # 119250KIT and hardwire it in.
view full answer... - 2004 GMC Yukon 4-Way Trailer Wiring RecommendationSounds like you are looking for a 4-way wiring harness for your 2004 GMC Yukon. The part # 41155 that you referenced will fit your truck if it has the round 7-way connector present behind the bumper. If you have no trailer wiring at all you instead would want the part # C59496. This is a hardwire kit that will fit your vehicle regardless of whether or not you have the round connector.
view full answer... - Where is the Tow Wiring Connection on a 2014 GMC Savanna VanThe 2014 GMC Savanna Van has two possible options for trailer wiring. If the van is pre-wired for a towing package or it is not pre-wired. The wiring plug that you mentioned does not look like the correct wiring plug needed if the vehicle is pre-wired for towing. The plug end for the pre-wired will be a OEM car connection that is a somewhat large round plug. See photo. If your vehicle is not pre-wired, then a harness kit like Tekonsha T-One Vehicle Wiring Harness, # 118392, will work...
view full answer... - Towing a Trailer with a 2018 GMC YukonI can help you with what you need to tow a trailer with your 2018 GMC Yukon, but from my research we do not carry a hitch for that vehicle because they include a factory trailer hitch. Your vehicle likely came with a factory tow package hidden under a cover in the center of the rear bumper. You should be able to remove that cover to reveal the trailer hitch receiver. You may also want to double check if your vehicle came with a wiring harness. We offer several quality wiring harnesses...
view full answer... - Easy Way to Add 4-Way Trailer Connector to Rear of 2014 Volkswagen Touraeg with Round ConnectorThanks 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.

- Recommended 4-Way Trailer Wiring Kit For 2015 Audi Q7 With Factory Tow PackageThere are a couple of trailer wiring kits that are designed for your 2015 Audi Q7. If the trailer has a 4-way connector and you have no need for a 7-way connector I recommend part # 41155. This just plugs into the connector at the rear of your Q7 behind the bumper. If you want a 7-way and 4-way connector then you could use part # HM40975. This kit uses the same plug at the rear of your vehicle and comes with a mounting bracket. You then have a working 7-way and a 4-way connector at...
view full answer... - Installing Tekonsha Vehicle Wiring Kit # 119250KIT on 2014 Audi Q7 with Factory Trailer WiringWhen 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...

- Adding a 4-Way Trailer Connector to a 2014 GMC Sierra 1500If your 2014 GMC Sierra came with a factory 7-Way you can use # 41155 to plug in a 4-Way in its place. Or you can use an adapter such as # PK12716. If your truck did not come with any trailer connector you would have to contact a GMC/Chevy dealer for the proper parts since there are currently no aftermarket 4-Way harnesses confirmed to fit your truck.
view full answer... - Connecting a 4-way Lighting Harness for Cargo Carrier to a 2013 Chevy Avalanche with Factory 7-wayIf you'd like to replace the 7-way trailer connector on your 2013 Chevrolet Avalanche you can do so with # 41155 that plugs into the same location your current 7-way does. Another option that will allow you to keep a 7-way is the # HM40975. This also plugs into the Avalanche's wiring but provides both a 7-way and a 4-way connector.
view full answer... - 4-Way Trailer Wiring Harness Recommendation for 2015 Chevy Silverado 1500There 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.
view full answer... - Wiring Harness for 2014 Chevrolet Traverse Without Factory Tow PackageThe Hopkins Wiring Harness Kit # 41155 is intended as a replacement for the harness included on the Traverse that HAS the factory tow package. If your 2014 Chevrolet Traverse does NOT have the factory tow package then the kit you need is # HM11141150. We do not have a video on this but I have linked a helpful article.
view full answer... - 2014 Audi Q5 Trailer Wiring RecommendationThe # 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.

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.
