Power Wire Kit for Electric Trailer Brake Controllers - 12 Gauge - BRK-ELECKIT

Average Customer Rating:  4.1 out of 5 stars   (8 Customer Reviews)

Use this wiring kit to power your trailer brake controller. Designed for vehicles that do not have power going to the built-in brake controller port.


The kit was missing the inline butt connector for splicing into the harness at the brake controller. The installation video says the butt connector is included in the kit. Fortunately I have butt connectors in my personal parts stash so I could finish the install.

Thanks for your review and letting us know - well be happy to send one out to you!
-- Etrailer Expert Victoria B - 10/02/2019


Just starting to install and not enough wire is included in this kit, therefore, I a, off to the store to purchase wire. I ordered this thinkinking it would have been less expensive to buying each thing needed individually, well so far, no!


Product was as stated. Spent the afternoon installing it. All I have left to do is mount the trailer brake control and then will be ready to go.


Great company , Excellent selection , Fast shipping !!!
I found my new accessories store !!!


Works great and I have zero complaints.

  • Solution for Powering Brake Controller Install of 2019 Ford F150 with Factory Tow Package
    This is a common issue for installing a brake controller in the 2019 Ford F-150 and the easy solution is to install the part # BRK-ELECKIT which bypasses the very mysterious brake controller power wire issue your truck has and allows your brake controller to draw power directly from the battery. Basically you cut out the black wire from the harness you have now and connect it the wire of this kit and then wire it directly to the battery with the included ring terminals. This bypasses the...

  • Can a Trailer Brake Controller be Turned Off
    Modern brake controllers such as the P2 # 90885 will go into a power saving mode after about 15 minutes of inactivity. In this mode the controller will only draw a few milliamps of power. At that rate it would take months of the vehicle just sitting for a brake controller to drain the vehicle battery. If it does not go into power saving mode that means that something is drawing power on the brake circuit. The most likely culprit is corrosion in or on the vehicle side trailer connector....

  • What Parts Will I Need to Install a Tekonsha Brake Controller on 2021 Ford F-150
    To install the Tekonsha brake controller on your 2021 Ford F-150, you will need a wiring adapter like the Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers # 22292. You can use this adapter if your F-150 has the factory 4-Flat or 7-Way. If you can tell me the model number of your brake controller and if you have factory tow package or not, I can tell you the exact adapter you will need.

  • Brake Controller Recommendation for 2018 Ford F-150
    To install our very popular P3 brake controller part # 90195 in your 2018 Ford F-150 will only require the correct install harness. For that you'd want the # 22292 which is a confirmed fit and simply plugs in under the dash. Some versions of your truck though don't have power ran to the brake controller port and would require you to also install the # BRK-ELECKIT. I attached an install video for this for you to check out as well.

  • Location of Brake Controller Connector for an Aftermarket Controller on a 2018 Ford F-150
    The location that you would connect an adapter like part # 22292 to your 2018 Ford F-150 for installing a brake controller like the Prodigy P3 # 90195 is behind and to the left of the center console area. If you remove the front panel that is directly under your steering wheel you can access the plug this way (see attached photo). Some models of the 2018 F-150 don't have power running to this brake controller port. If this is the case for you then you would need the wiring kit # BRK-ELECKIT...

  • Can A Tekonsha Brake Controller Be Installed On a 24 Volt Electrical System
    Yes, it is possible to install a Tekonsha brake controller like the Tekonsha Primus IQ Trailer Brake Controller part # TK90160 which is what I recommend on a 24 volt system. In order to do so you will need to obtain a 24 volt relay from your local automotive parts store and then some various primary wire, circuit breakers, and wire connectors like what is included with the Power Wire Kit for Electric Trailer Brake Controllers part # BRK-ELECKIT. I have attached a diagram for you to assist...

  • Will the Curt Echo Brake Controller Work On a 2019 Ford F-150
    The Curt Echo Mobile Trailer Brake Controller part # C51180 will work with a 2019 Ford F-150. However, the 2015+ Ford F-Series Pick-Ups have what is called a SmartTow feature that prevents power from supplying the trailer connector most of the time. Therefore, in order to use the Curt Echo on a 2016 Ford F-150 you will need to run a dedicated power wire from the battery to the trailer connector and all you will need for this is the Power Wire Kit for Electric Trailer Brake Controllers part...

  • Does Computer of 2019 Ford F-150 Need Flashed to Install Aftermarket Brake Controller?
    If you install the Prodigy P3 # 90195 you will not need to have the computer flashed. In most models it will simply plug in using the Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers # 22292, however some do not have power run to the brake controller port under the dash. If this is the case, we have wiring kit # BRK-ELECKIT which you can use to run power to the brake controller port. I've attached a video to help with all of this.

  • Does Computer Need To Be Flashed When Installing Brake Controller On 2021 F150?
    The OEM brake controller requires your 2021 Ford F-150 to be flashed by the dealer. However, an aftermarket brake controller like the Tekonsha Prodigy P3 Trailer Brake Controller - 1 to 4 Axles - Proportional # 90195 does not require the dealer to flash your truck's computer. You will need Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers # 22292 to connect the brake controller to the factory plug-in on your truck. Keep in mind, not all 2021 models have the necessary 12V going...

  • Tekonsha TK90160 Primus Brake Controller Not Powering Up When Installed in 2020 Ford F-150.
    For whatever reason, some F-150 models will have the plug in the dash for the brake controller, but the 12 volt power feed to that connector hasn't been connected. You may need to add a 30A fuse in the distribution box under the hood, in location # 24. If location # 24 is NOT pinned, you'll need to run your own wire to the controller. We offer a kit, part # BRK-ELECKIT that will correct this. I've provided an install link for a different controller, but the procedure for your # TK90160...

  • Which Circuit Breaker Needed to Install Curt C51180 Echo Brake Controller on 2012 Toyota Highlander
    If you'll be installing the Curt # C51180 Echo Wireless Brake Controller, you'll want to use a 30A breaker, like part # 38630, you'll also need 12 gauge wire, ring terminals and butt connectors. We actually sell all this in a kit as part # BRK-ELECKIT. I've linked to a video explaining how the Curt Echo brake controller works, as well as to a video that will run you through the install.

  • Parts Needed to Run Power Circuit for Installing Curt C51180 Curt Echo Wireless Brake Controller
    Using 12 ga wire is indeed acceptable for installing the Curt # C51180 Echo wireless brake controller, but to protect the power feed circuit you'll want to use a 30A self resetting circuit breaker instead of a fuse. We sell the wire, hardware and breaker in a kit, as part # BRK-ELECKIT. If you already have the wire and hardware, we sell the breaker separately as part # 38630.

  • ETBC7L Without 7-Way for Autowbrake Brake Controller
    There is a kit that has exactly what you need with the hardware without the 7-way of the RV Upgrade Kit # ETBC7L. What you need is the Power Wire Kit for Electric Trailer Brake Controllers # BRK-ELECKIT. This has everything you are looking for, minus the 7-way, so you can install the Autowbrake Electric Brake Controller # 3430001. In regards to the power wire, it will not charge the trailer battery, but it will maintain the battery's charge while you are towing.

For this installation I also recommend the Power Wire Kit for Electric Trailer Brake Controllers - 12 Gauge # BRK-ELECKIT and the Air Line Hose 1/4" # RM450700 sold by the foot.

  • Installing an Aftermarket Brake Controller on a 2021 Ford F-150
    Installing an aftermarket brake controller, like the Tekonsha Primus IQ # TK90160, is definitely possible. That being said, not all of the 2021 models have the power run to get the controller up and running, so you may need to add # BRK-ELECKIT. This will add the power needed and is not very difficult to install. Especially since your vehicle will have a factory port under the dash. The Tekonsha # 22292 will plug directly into this port and then directly into the back of the # TK90160. To...

  • How to Wire Curt C51180 Echo Brake Controller for Power
    It's pretty simple to install the power connection for the Curt # C51180 Wireless Brake Controller. We actually offer a kit that offers everything you need, part # BRK-ELECKIT. The kit includes the wire, inline circuit breaker, hardware and even the zip ties needed to complete the installation. We also offer a full kit that includes the 4 pole to 7-way adapter as part # ETBC7L. I've linked to an install video and a help article that you might find helpful.

  • Curt C51180 Echo Wireless Brake Controller Showing 'Vehicle Battery Low' Error
    I believe the reason your controller is behaving the way it is is the lack of a direct battery connection. Pressing the brake pedal feeds some power to the unit that disappears once you let off the brake pedal. In order for the Curt # C51180 to work correctly, it does indeed need a direct battery connection for the pin in the 1:00 position on the 7-way trailer connector. If you don't already have a direct connection, you can set it up using # BRK-ELECKIT which includes the 30A breaker...

  • Are Some Versions of the 2021 Ford F-150 Not Able to Have Brake Controller Installed
    On some models of the 2021 Ford F-150 the brake controller install port is present but there just isn't any power ran to it for some reason. The solution for that is to use the part # BRK-ELECKIT which gives you the parts needed to activate this circuit. Basically it's a 12 gauge wire with a circuit breaker that runs up to the vehicle battery. To install the # TK90160 you referenced you'd also need the part # 22292 then. We've also seen that the versions of the 21' F-150 made earlier...

  • Redarc Tow-Pro Elite Brake Controller For Towing A Horse Trailer With a 2021 Ford F-150
    The reason that the Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR is not good for the manual override is that when you drive with the controller in proportional braking mode and push the manual override it only allows the trailer brakes to be applied in a light braking scenario. This is often not enough braking force on the trailer brakes if you are relying on them solely. As you are new to trailering and brake controllers I do not see this being an issue for you as it comes more...

  • Adding a 7-Way Connector and Brake Controller to a 2018 Ford F-150 with Factory 4-Way
    I will be happy to get your 2018 Ford F-150 set up with a 7-Way trailer connector and a brake controller. The method for doing so that requires the fewest parts is to hardwire in the brake controller/7-Way. Since your truck already has a factory 4-Way connector you will just need # ETBC7 to add a 7-Way, retain the 4-Way, and have the parts needed to install a brake controller as well as run a 12 volt hot lead. If you do not already have a brake controller picked out I recommend the P2...

  • Installation of Brake Controller and Brake Controller Wiring to Added 7-Way in 2018 Ford F-150
    For your 2018 Ford F-150 I don't recommend the Curt Venturer brake Controller # C51110 but it will install in the same way as any other brake controller and for that installation you have a couple different options. If when you installed the 7-way you grabbed the factory wiring for your 12V and brake controller from near your driver's side wheel well, then I recommend using the wiring harness # C51436 which will connect to the factory port under your dash. Some models don't have the brake...

    Thank you for the pictures! Based on the pictures you sent I believe you have the Hopkins Endurance Multi-Tow 4-Way Flat to 7-Way RV Trailer Adapter w/ 4-Way Vehicle End Plug # HM47180. You are correct that the Red wire from the adapter will get connected to the battery on your 1993 Toyota T100 Pickup, and since you are using the Curt Echo Wireless Trailer Brake Controller # C51180 you will need to use 12 gauge wire and a 30 amp circuit breaker which can be purchased as a kit # BRK-ELECKIT....
