• 7-Way Upgrade Kit to Install Curt Echo Brake Controller and Provide 12V Power for Trailer Battery
  If you have a 4-pole wiring setup now and you want to install a wireless trailer brake controller you will use an adapter like Curt # C57672 or Hopkins # 37185. Both install by plugging in to your 4-pole and by making additional wiring connections using the pigtail leads. If you want to use a wireless smartphone-controlled brake controller like the Curt Echo # C51180 you will not need to run a blue brake output wire. All you'll need to do is provide a 12V power connection to the adapter....

• My Vehicle has a 4-Pin Trailer Plug, but Trailer has 7-Pin Trailer Plug
  If you just need a 4-pin to 7-pin trailer wiring adapter, then you can use part # C57672. This will plug into the 4-pin trailer connector on your brother's vehicle and give him the 7-pin socket for the trailer. Keep in mind, this will only give you trailer light functions. If your trailer has a 7-pin connector, then it likely has electric trailer brakes and an onboard battery. If you want a fully functioning 7-way trailer socket on his vehicle, then the installation will be a bit more...

• Can Curt Echo Brake Controller be Installed in 4-Way/7-Way Adapter and Still Work
  That's actually a really good question! All the Curt Echo # C51180 needs to operate properly are the basic trailer lighting functions (found on a typical 4-Way), and then 12V power. If you already have a 4-Way/7-Way adapter like part # C57672 then all you'll need to do is run a length of 10 Gauge Wire # 10-1-1 to a 30A Circuit Breaker # PK54530 and then to the positive battery post on your tow vehicle. If you don't already have an adapter then you can just get the Upgrade Kit # ETBC7L...

• Brake Controller Installation on 2018 Toyota Highlander
  You'll need to choose a brake controller and the # ETBC7 brake controller installation kit. The install kit includes an adapter to convert the 4 pole you recently installed to a 7-way. I'd recommend a proportional controller like the Tekonsha Primus, part # TK90160. Your Highlander is very sensitive to power feeding back into the brake lamp circuit, so instead of the pigtail included with the Primus, you'd need to use the # 7865 which has a diode installed on the brake lamp circuit to...

• Do the Blue, Yellow, and Black Wires Need To Be Run On the Curt Trailer Connector Adapter C57672
  For starters, we do not offer products through Amazon as they are a competitor of ours. However, I can offer you the Curt Trailer Connector Adapter part # C57672 which will work on your 1968 Ford F-150 if you have an existing 4-way trailer connector. The additional black, yellow, and blue wires do not need to be attached in order for the trailer light to work but you will need to ground the white wire to your frame. The black wire is to charge a battery on the trailer and you will need...

• Easy 4-Way to 7-Way Brake Controller Solution for 2020 Kia Sorento
  To activate trailer brakes you do have to have a brake controller installed in your 2020 Kia Sorento. I do have a really easy solution thought that uses a similar adapter to the # C57672. So for a brake controller I recommend the Curt Echo Mobile # C51180 which basically plugs into an active 7-way and once synced to a smart phone can easily activate trailer brakes. Now the 7-way adapter kit you'd want instead is the # ETBC7L which comes with a similar 4-way to 7-way adapter and also...

• Can You Extend the Ground Wire When Installing Trailer Wiring?
  The Curt Trailer Connector # C57672 should be grounded to any paint and debris free surface, preferably the vehicle frame; since the hitch is painted, it's not going to provide the best ground source for your 7 way connection. You can extend the ground and run it to a more convenient spot on the vehicle and you'll want to use a ring terminal like # 44-5356A (similar to the one found on the end of the ground wire of the C57672). If you need additional wiring, you can use # 10-1-1 which is...

• Brake Controller Installation on 2000 Cadillac DeVille
  You can indeed install a brake controller on a 2000 Cadillac DeVille. As a first step, you'll need to access the taillight wiring circuits. The best and safest way to do this would be to use a powered taillight converter like # 119147KIT. You could directly wire into the taillight circuits using a wiring kit like # 18252, but you'd lose the circuit protection offered by the taillight converter. The converter would protect the electronics in your vehicle from any short circuits that might...

• How Does 7-Way Trailer Adapter with 4-Way Connector Install
  What you have pictured is a 4-way to 7-way adapter similar to part # C57672. The male side 4-way connector plugs into a vehicle side (female) 4-way to convert the vehicle's connector to a 7-way. The existing 4-way on the vehicle only has the lighting functions so the rest of the wires need to be hardwired to make the 7-way completely functional. The additional wires are to power reverse lights (yellow), the 12 volt auxiliary pin (black), and electric brakes (blue). The white wire is...

• Cost Effective Wiring To Install 7-Way For Curt Echo Controller on 2008 BMW X5 With Battery in Trunk
  The Curt Trailer Connector Adapter part # C57672 can certainly be used to install a 7-Way on the 2008 BMW X5 to use the Curt Echo Wireless Brake Controller part # C51180 instead of the kit part #ETBC7L. I recommend to use the Curt trailer connector part # C57672 and the Power Wire Kit for Electric Trailer Brake Controllers part # BRK-ELECKIT because it has a shorter amount (10 feet) of 12 gauge wire since your battery is in rear cargo area. This kit also comes with all of the components...

• Easy to Install Brake Controller Recommendation for 2009 Ford Escape
  The easiest to install brake controller to use with the 4-way to 7-way adapter # C57672 is the Curt Echo Mobile controller part # C51180 which would require you to only complete the black wires circuit of the adapter and you'd be set.

  The Blue Ox Patriot 3 Radio Frequency, Portable Braking System - Proportional # BRK2019 needs power for proper function, so it does require a direct connection to your battery which isn't an issue on your 2015 Ford Flex.

• Can I Use Both The 7-Way and 4-Way At The Same Time?
  I have a solution for you, but you won't be able to use both the 7 way and 4 way plugs on the Hopkins # HM40975-11998 at the same time because the cover flaps do not allow for both to be open simultaneously. In order to plug both your 7 way and 4 way into the same plug you would need to use the Curt Trailer Connector Adapter # C57672 , which has the plugs side by side with dust caps that flip up to allow you to connect your plugs as desired.

• How to Add 7 Way Plug for 2016 Honda Pilot
  In order to complete the installation of the Curt 4/7 way connector # C57672 you will need to finish connecting the black, blue, white and yellow wires on that connector to give you a working 7 way.

Without utilizing the factory wiring for your 7 way, which you won't be when installing the Curt # C57672, you will need to hard-wire in...

• Comparing 4-Way to 7-Way Adapter and ETBC7L Kit
  The main difference is just what you said, the # A10-7084VP is only the adapter and the # ETBC7L includes the bracket, connectors, a circuit breaker, and 20 feet of wire. The other significant difference is the adapter included with # ETBC7L has a 4-way and a 7-way so you don't lose the existing 4-way on your vehicle which is important to some people. It's similar to part # C57672 which also includes the bracket but not the other parts of the # ETBC7L

• Parts Needed to Install 7-Way Wiring on a 2014 Audi Q5
  While there are no plug and play type 7-Way connectors for your 2014 Audi Q5, we still have the parts you need to get a 7-Way installed so you can tow your trailer.

• Why is 12 Gauge Wire Used in ETBC7L Kit Instead of 10 Gauge?
  The 7-Way RV Upgrade Kit for Trailer Brake Controller Installation - 12 Gauge Wires # ETBC7L comes with the 30 amp circuit breaker and 20 feet of 12 gauge wire. For a run over 20 feet, I do recommend updating the wiring to 10 gauge using # 10-1-1 sold by the foot and using the 40 amp circuit breaker # 9510 instead. You can still use the Curt Trailer Connector Adapter - 4-Way to 7-Way RV and 4-Way Flat # C57672 for the connector and this will upgrade your amperage capacity. The 12...

• Pop up trailer brake light and turn signal on right side not working
  I recommend checking the fuses under your dash. Some vehicles will have separate fuses for each function. My uncle had the same issue. I advised him to check the fuses first and he determined that he had a fuse blown. If your fuses are not the issue then check your 7 pole plug on the back of your Tacoma again. Have someone run through all the functions and test each one. You may be getting power to the plug but each function is going to be separate. If your determine that some of your functions...
