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.

In height or total diameter, a 185/80-13 and 175/80-13 like part #AM1ST77 only differ by about 5/8 of an inch. The 185 would have a diameter of 24.65 inches while the 175 would have a diameter of 24.02 inches. The section width, or thickness of the…

Trailer tires in sizes 175/80-13 and 185/80-13 will fit the exact same wheel sizes. You can have the 175 mounted on the wheel and use it as a spare but you would not want to run different sizes for long. I have included a link to some trailer tire…

On each individual electric brake magnet the amperage draw would be 3.0 to 3.2 max amps at 12 to 13 volts on 7-inch brake magnets and 3.2 to 4.0 max amps at 12 to 13 volts on 10 and 12-inch brake magnets. The max amperage draw for the brake magnets…

I think you are going in the right direction. I would definitely replace the 14 gauge wire going to the trailer brake magnets with 10 gauge wire or larger. Usually larger than 10 gauge is hard to get into the trailer connector though. I would also…
