4-Way to 7-Way Adapter Recommendation for Installing Curt Echo Brake Controller

Question

Question:

Other than the white ground on the Curt 57184 adaptor, do I need to use any of the remaining 3 wires black, yellow, and blue after plugging in the 4 pin connector in order for this Curt C51180 to control my trainers electric brakes? If yes, what ones and what to they connect to? I have a 08 Toyota Highlander and 10 Toyota Tacoma that we were planning on converting from 4 pin to 7-way and using this bluetooth brake controller to tow on either vehicle.

If your plan was to install a brake controller you'd have to also run the black wire of the 7-Way Adapter part # 30717 to the to the positive post of your vehicle battery as well as the ground you mentioned. The Curt Echo part # C51180 that you referenced needs the black wire to power it and then uses the other signals from the 4-way adapter to tell when the vehicle brakes are on.

For a different adapter that comes the extra wire and breaker to activate the needed circuit for the Curt Echo you'd want the part # ETBC7L instead. This kit was basically put together for brake controller installs like the Curt Echo that are wireless.

I have a 7 way plugged into my 4 way plug. Will the C51180 work as it's made to do?

The Curt Echo # C51180 will plug into your new 7-Way but you still need to activate the 12V circuit. You can do this by running some 10 gauge wiring # 10-1-1 from the 12V pin on the 7-Way up to the vehicle's positive battery post via a breaker like # 9510.

There are a few differences between the Universal Installation Kit part #ETBC7 and the 7-Way RV Upgrade Kit part #ETBC7L. The biggest one is that part #ETBC7 comes with both the power and brake output wire you will need to run to the cab/battery…

Hey Ray, so we have the part #18159 which would work great to secure the 7-way of the #ETBC7L that you'll be installing with the Curt Echo #C51180. It's also pretty easy to install too.

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…

If you purchased a 4-Way/7-Way Hopkins adapter like part #37185 so that you can use the Curt Echo Mobile Trailer Brake Controller #C51180 then you are correct about only needing to connect the 12V power wire for the brake controller (in addition to…

Answer 10

The #ETBC7 or #ETBC7L will differ from the Curt #C57672 in that these two parts both come with all of the wiring, breakers, mounting bracket and connectors needed to complete the job; the Curt #C57672 is just the 7 way connector without any of the…

Answer 11

You assumed correctly. The Blue and Yellow pigtail leads on the Curt Adapter Item #C57672 do not have to be connected to use the Curt Echo item #C51180. You will just need to connect the 4-way to the adapter and then run the ground and power wires.
