Parts Needed to Complete Installation of 7-Way Adapter on 2010 Honda Odyssey
Products Featured in This Question
Question:
Hi there, I bought a Rockwood trailer that has electric brakes. I have a 2010 Odyssey without the tow package. I purchased the 4 way to 7 way connector and the Curt bluetooth brake controller. My question is how do I connect the brake and power wires from the 7 way connector to my van? Thank you

If you only bought the adapter the first thing you're going to need is an actual 4-way on your 2010 Honda Odyssey. The # 118438 will plug into the connection point in your rear cargo area. Once this is done, you can plug the 4-way end into your 7-way adapter to carry over the signal functions for your trailer.
After that, you will need the Wiring Kit for 2, 4, 6, and 8 Brake Electric Trailer Brake Controllers # 5506. This comes with everything you need to complete the installation of your 7-way adapter. If you have the Curt Echo Under-Dash # C27JR you will need to connect the 12V power and brake output wires. If you're using the Curt Echo # C51180 you do not need to connect the blue brake output wire since it installs at the 7-way.
I have attached some installation videos below for your reference.

Thank you Robin. My Odyssey already has the 4-way connector installed. I'm trying to install the 7-way but need to also install the brake wire as the trailer I purchased has electric brakes. I bought the Curt C51180. So my question is where do I install the blue brake wire from the 7-way connector into my vehicle? I was hoping not to have to drill or run wires, hence why I bought the Curt C51180.
