Can I Use a 4 Way Vehicle Connector with 7 Way Adapter and the Curt Echo Brake Controller?  


Can I use a 4 way flat to 7 round adapter and the Curt Bluetooth brake controller


Expert Reply:

It sounds like you may already have a 4 way connector on your vehicle, which is half of the battle. In order to operate the Curt Echo Mobile Wireless Brake Controller # C51180 you will need an almost fully functional 7 way connector; using something like the Hopkins # 37185 adapter from the answer you were looking at would work, but it doesn't come with all of the wiring you'll need so I don't recommend using that and you will need to run a power wire to your battery (not included).

Instead, I recommend using the # ETBC7L, which has all of the wiring you'll need to easily install a 7 way connection on your tow vehicle capable of powering the Curt Echo brake controller. This kit will use your existing 4 way to plug into the light functions and then you'll just need to run a wire to the battery and reverse light functions to have the connections you need.

I've linked one of our helpful videos that runs through how to install an ETBC7L connector and since you've already got a 4 way on your vehicle, the process should be relatively easy.

Why couldn't you use the one he has and just run your black 12 gauge wiring that I already have to battery, and save $60,,,,,it's just $60 for the extra 12gauge black wiring to run to battery???or am I missing something

@Drew Yes that would work. Or we have the version of this adapter specifically for the Echo with the part # ETBC7L.
