Does Brake Output Circuit of 7-Way Need to Be Active for Curt Echo to Function

Question

Question:

I’m installing a Curt echo wireless brake controller on my ford ranger. I do not have a 12 vol power wire currently connected to my 7 pain truck re eptacle. The trailer brakes on on a 10 gauge wire T terminating at the trailer 7 point plug. Question: I’m assuming I can run a 10 gauge wire from my battery, thru a circuit breaker to the terminal that matches my trailer blue wire terminal,, or do I run it to the center terminal on the Curt echo? What size circuit breaker do I need, 30 or 40 amps? Thanks, Larry

Hey Larry, the Curt Echo # C51180 does not need the blue wire circuit to be completed at all on the vehicle side as it basically provides that circuit. It does need to have the 12 volt power circuit active though so you would need to have the pin in the 1:00 position connected to the vehicle battery through 10 gauge wire like part # 10-1-1 and a breaker like part # 9510.

Hey Larry, how did things go getting the 12-volt power wire and circuit breaker set up for your Curt Echo brake controller? Your update could make it easier for others wiring the same setup on their trucks.

You'd want to use 10 gauge wire like part #10-1-1 which we sell by the foot. Attaching to the battery is a matter of going directly to the positive post of the battery and you'd be set.

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 need to run the power wire of the #ETBC7L kit and of the trailer wiring kit part #118599 separately as they at any given moment you could over draw the wire if both circuits were pulling their max amperage.

Since your plan is to use the Curt Echo part #C51180 the 4-way to 7-way adapter you need is the part #ETBC7L which was made with the Echo in mind. It comes with the correct size breakers and wire gauge that the controller needs which happens to be 12…

Answer 10

The wire that comes with the 7-Way RV Upgrade Kit for Trailer Brake Controller Installation #ETBC7L for the power circuit for the Echo #C51180 is 12 gauge. I would agree that 10 gauge would probably be more ideal for carrying a brake output circuit.
