Which 4-Way to 7-Way Trailer Wiring Adapter Allows Trailer Battery Charge Circuit to Activate

Question:

Thank you for your response. I do have a couple follow-up questions regarding using the ETBC7 7 Way RV Upgrade Kit. Is it compatible with the Curt Echo #C51180 Brake Controller? I’m looking at the Curt Echo since it doesn’t have to be mounted inside the vehicle. My 2018 Subaru Outback doesn’t appear to have a good place to mount a brake controller due to all the safety features, buttons and the display. You recommended a Prodigy brake controller. Do you consider this to be better than the Curt Echo?

Since your plan is to install a brake controller and want to charge the camper battery what you need is actually the part # ETBC7. This comes with basically the same things as the # ETBC7L except it also includes wiring and circuit breaker to complete the brake controller circuit that you use for charging the trailer battery.

I attached a video that shows this kit installed on a similar 2011 Subaru Outback for you to check out as well. The brake controller in the video is our best selling Prodigy P3 part # 90195.

The Curt Echo # C51180 is really a great solution. I'd recommend it highly for you. The P3 is really nice but the Echo is really convenient and applies the brakes proportionally just like the P3.
