Question:

I have a trailer with 7 pin connector with brakes. My vehicle has a flat 4 pin connector so it looks like I need #57672 do I also need to hook up the other wires to use my wireless curt brake controller saw a kit #51500

Expert Reply:

It sounds like you are definitely on the right track here. You would plug the Adapter # C57672 into the existing 4 flat plug. Then the Kit # C51500 contains the rest of the wires you will need to run to upgrade to a 7 way. From there you will be ready to plug in and use a wireless brake controller like the # C51180.

Since the Curt echo works off of the vehicles brake lights, technically you would only need to connect the 12v wire to the 7 way plug in order to use it. The additional wires would only need to be run to the front of the vehicle if you plan to use an in-cab brake controller like the Tekonsha P3 # 90195.
