Parts Needed to Run 12-Volt Circuit to Install Curt C51180 Echo Brake Controller  

Updated 03/19/2021 | Published 03/17/2021



Question:

Hello, I have a 7-pin adapter for the 4 flat wiring on my 2013 Dodge Grand Caravan. I am planning on purchasing the wireless Curt trailer brake, part number C51180, however I still need the wiring for the power to run to the brake circuit on my 7 way. As well as the 12 volt circuit. I was hoping there was some wiring I could purchase that would work for this, so I do not have to buy an entire 7 way kit again. Thank you, I look forward to a response.

Since you already have the # 37185 adapter, all you'll need to do to install the Curt # C51180 Echo wireless is run a 12V circuit from the black wire on the adapter to the positive battery terminal via a 30 amp circuit breaker like # PK54530. You'll need a length of 12 gauge wire long enough to run from the trailer connector, up under the vehicle into the engine compartment and to the battery. We offer 12 gauge wire by the foot as part # 12-1-1.

You'll also need 2 small ring terminals like # 44-5310A to make the connections at the breaker and one large terminal like # 44-5356A to connect to the positive battery terminal.

You won't need to run a brake circuit, the Echo gets its brake signal from the trailer brake lamps and determines how quickly to send voltage to the brakes based on its internal accelerometer.

I'll link to some demonstration videos that you might find helpful.
