I ordered this wiring kit for a 2003 Dodge Ram 1500 I recently acquired. The Ram was not tow ready but did have a factory 4-way. I also ordered hitch #13333. The wiring kit is very high quality and was easy to install. The 7-way fit perfectly where the factory 7-way would have gone. I'm using a Tekonsha Prodigy RF wireless brake controller so the blue lead was not needed but I left some extra should that change. Thanks etrailer!

Excellent!! I lovbe it

I was skeptical about this purchase at first, but when I thought of all the parts I was going to have to round up at our local auto parts store, whether they had them in stock, and if they had to order them, I decided to get this product from etrailer. I am very glad I did as I found out the existing 7-way plug on my truck had lots of rust/corrosion and the ground wire was almost rusted off its connection points. It is nice having all of the connections already in the 7-way plug and the product arrived in just 2 days with standard shipping! The directions that came with this product were very helpful! I won't hesitate to ordering from etrailer again. I also purchased C51140: Curt TriFlex Trailer Brake Controller to go with this. Works great!



by:

Great product and very easy to understand the installation instructions. Very quick shipping. My 2013 Ford F-150 had no factory wiring and this is gonna give the 7-way I need

Great



by:

used on chevy express van works well, van was not prewired for trailer connections or brakes this was my only option, installation took awhile for connections under hood and dash, circuit breakers mounted under hood greased up w/ dielectric grease so far so good made it through 1 Michigan winter



by:

This trailer brake wiring harness worked very well on my wife's 2013 Chevy Equinox, and the videos and instructions Etrailer provides for nearly everything they sell can't be beat. Have been using this since April 2020.



by:

This product made life real easy converting a standard 4-way plug into a 7-way blade plug and adding a Tekonsha P3 trailer brake controller on my motorhome (1993 Monaco Dynasty). It solved several problems, now I do not have the buy (and have installed) a tow bar and pneumatic brake system for the pickup, just load it up on the car hauler and go (with brakes). Follow the instructions & wiring diagram (simple); the hardest part (not that difficult) of the job was running the controller wire to the front of the MH. Thanks George.



by:

The 7 way trailer light system and brake controller- installed easily and worked well with our pop up trailer.



by:

Used this and other items to install an RV connection with bake controller in a Subaru Forester that had a factory hitch and four way trailer connection.



by:

It was not entirely clear about what to do with the blue wire in the instructions. The blue wire must connect to the controller for everything to work. Other than that, its a decent kit



by:

etrailer videos make installation easy, took 2 hours and saved hundreds. Put the trailer brake controller on and now have my eyes on air suspension through etrailer.



by:

The 7 way break connector I received was equipped with excellent instructions and all parts needed to hook up I had no problem installing and works excellent I would give 5 stars



by:

Installed easily and have had no problems over the year I have used this wiring harness.

  • Installing Tekonsha Prodigy P3 In A 2022 Toyota Highlander XLE Without Factory Tow Package
    Hello Paula. To install a Tekonsha Prodigy P3 in your 2022 Toyota Highlander you will just need to install a 7-way harness. I recommend the Tekonsha OEM Replacement Vehicle Wiring Harness # TK57VR. This will come with everything you need to wire your vehicle with a 7-way, including all of the necessary wires for connecting your P3 brake controller.

    Hey John, I can definitely help with that. The Reese brakeman controllers are compatible with the Tekonsha brand plug-and-play adapters. For your 2002 Ford E250 you can use the # 3035-P to plug directly in to the factory brake controller plug. You will also need item # 37185 to complete your wiring. The brake (blue) wire will need to be run from the brake controller back to the plug in the rear. The brake controller power and brake pedal wires are already run. A 12 volt hot lead from the...

  • Parts Needed For Adding A Brake Controller To a 2017 Subaru Outback Wagon
    While the Curt Universal Installation Kit for Trailer Brake Controller # C57186 will give you everything that you are needing, I prefer the etrailer Universal Installation Kit for Trailer Brake Controller # ETBC7 for your 2017 Subaru Outback. Our trailer connection will give you a provision that will allow you plug into a 7-way or 4-way flat trailer without unhooking any wiring or using a separate adapter. And our kit will include a mounting bracket for the 7-way so you wont need to purchase...

The P3 offers the advantages of a large clear display, brake power settings you can store and call up on demand and an outstanding record of reliability. The P3 will install using kit # ETBC7 as shown...

  • Recommended Universal 7-Way Kit for 2010 Toyota RAV4
    You are exactly correct in that you can use either the Curt Installation Kit # C57186 or the Universal Installation Kit # ETBC7 to install a brake controller and fully functional 7-Way from the 4-Way you already have installed. These are both universal 7-Way kits that will work on your 2010 RAV4. Between the two kits, I actually recommend going with the # ETBC7. This is because unlike the Curt Kit, this will include a circuit tester to help with installation, along with a bracket to attach...

  • Does Curt Universal Installation Kit # C57186 Include Wiring to Activate 12V Pin on 7-Way
    If your vehicle is equipped with a 4-Way connector, the Curt Universal Installation Kit # C57186 that you referenced includes everything needed to convert it to a fully-functional 7-Way. This includes the needed 10 gauge wire that you will connect to the vehicle's positive battery post via the included 40 amp breaker to activate the 12V pin on the 7-Way. This is the terminal you will use to charge the battery on your trailer while you are towing. I have attached the complete written installation...

  • Is Red Wire Needed on Curt Brake Controller Installation Kit
    The red wire coming out of the 7-way on the Curt Universal Installation Kit for Trailer Brake Controller # C57186 is for the reverse light circuit. If you do not have this function or don't want to use it then no, you do not have to and can simply tie it off. I've added a link to the written instructions as well as a video review of this kit for you to check out.

  • Should I Always Have Power On Blue Wire After Installing Curt TriFlex Trailer Brake Controller
    The only time you want to see power on the blue brake wire from the Curt Triflex Brake Controller part # C24VV is when the brake pedal depressed in the vehicle or the brake controller manual override is activated. If the blue wire has a constant 12V then it is an indication that there is an issue with the wiring. This could lead to your trailer brakes locking up, getting hot or not working at all once you hook your trailer up. I was able to find your account and it looks like you used...

  • Troubleshooting Brake Controller Output on the Curt Universal Installation Kit # C57186
    It sounds like the brake controller output on the 7-Way of the Curt Universal Installation Kit # C57186 isn't functioning properly. This is probably the result of some damaged wiring but would start off by checking the brake controller pin and the pin for the 12V power (since those wires are run together) just to make sure. Using a circuit tester # PTW2979 test the pins in the 1 o'clock and 5 o'clock positions for functionality (see attached photo). The 12V power pin will have constant...

  • Easiest to Install 7-Way and Brake Controller for a 2010 Toyota FJ Cruiser
    Yes, we have a 7-way trailer wiring harness for you that uses the existing 4-way trailer connector and we have a brake controller that does not require you to splice into the stop light switch circuit. For this, I recommend using the Curt Universal Installation Kit for Trailer Brake Controller part # C57186 along with the Curt Echo Mobile Trailer Brake Controller part # C51180. The Curt Universal Installation Kit will plug into the 4-way you have now as mentioned above and the only other...

  • Does Curt Universal Brake Controller Install Kit # C57186 Come with Battery Charge Line Components
    Yes, the Curt Universal Installation Kit for Trailer Brake Controller # C57186 that you referenced does come with everything needed to run charge line for trailer battery charging. What this comes with that's related to that is 10 gauge wire plus a 40 amp circuit breaker needed to activate this circuit. I attached a review video link to this page for this kit for you to check out as well.

  • Can Curt 57186 7-Way Adapter Work with Curt 51180 Echo Wireless Brake Controller
    Yes, you can use the Curt Universal Installation Kit for Trailer Brake Controller # C57186 instead of the # ETBC7L to install the Curt Echo Mobile brake controller part # C51180. You'd do exactly like what you mentioned. You'd wire up just the black wire to the vehicle battery with the included wire and 40 amp breaker and you'd be set.

  • Wiring And Brake Controller Needed For A 2006 Chevy Express Van 1500
    Hey RJ, For the 4-pole wiring I recommend the Tekonsha T-One Vehicle Wiring Harness # 118392. This comes with plug-in connectors for a fast and easy installation. From there you'll want the # ETBC7 to get the 7-way. It will plug into the Tekonsha 4-pole connector and have a few more wires to run. I've attached videos for both of these harnesses to help walk you through the installation process. I do recommend picking up a no-drill bracket # 18136 to make mounting the 7-way on the trailer...

    The Curt Universal Installation Kit # C57186 is universal and will work on your 1997 Chevrolet Silverado 1500. It does not have a mounting bracket for the 7-way and will require you to already have a 4-way Trailer Connection # C55315. I recommend using the Universal Installation Kit for Trailer Brake Controller # ETBC7. Our kit will include the mounting bracket for the 7-way and on the trailer connector there is a separate connector for 4-way trailers. This means that you will not need...

  • Installing Curt 7-Way C57186 to 2007 Dodge Ram With Factory 4-Flat
    Since you mentioned you already have the plug under the dash but not a 7-way, I am going to assume your 2007 Dodge Ram has the factory 4-way. If that is the case, you just need to plug in the 4-way and connect the blue brake wire to the Curt Universal Installation Kit for Trailer Brake Controller # C57186. The blue brake wire is often located under the driver's side of the vehicle, right behind the front wheel well, and I have linked a help article below which details exactly what you...

  • How to Add a 4 and 7-Way Trailer Connector to a 2011 Ford Ranger
    The best option I have for you to add a 4-way trailer connector to your 2011 Ford Ranger is with the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 56014. The reason that this is the best option is because it does not require any cutting/splicing, it will just plug in behind each of your taillights. If the trailer you will be towing with your Ranger has brakes then you will also need both a 7-way trailer connector and a brake controller. For a 7-way,...

Therefore, as long as the camper you are looking at has brakes or you add them then yes you can safely tow the trailer with this vehicle. In order to tow a trailer with your Forester you will need a trailer hitch, wiring harness, and ball mount/hitch ball. For a trailer hitch I recommend the Curt Trailer Hitch Receiver...

If you are looking to tow under 5,000 lbs then all you would need is a hitch ball like the 2" Hitch Ball part # 40038 or the 2-5/16" Hitch Ball part # C40007.
