Question:
Hey guysi have a 3800 gvwr trailer with a 375-425 tongue weight pulling with a Toyota highlander. Currently I have the curt Bluetooth break controller and was interested in the curt anti swaybsystem. Was wondering how power got to the sway system with the break controller installed. Does that plug into my vehicle then the sway system plug to that, then my trailer plug into that? Just wanted to make sure everything would be compatable together and how things work before I made this fairly expensive purchase Thanks in advance Chris

Hey Chris!
The Curt True Course Advanced Bluetooth Trailer Sway Control - 1 to 4 Axles # C94VV is powered through the 7-way connector on your Highlander. With that, you can use it in tandem with a wireless brake controller like Curt Echo Wireless Brake Controller - 7-Way Plug-in w/ Bluetooth App - Up to 2 Axles - Proportional # C51180 and they'll both be able to be monitored through the Curt OneControl app.
The order that you would install them would be the Curt Echo brake controller directly into the vehicle, the True Course sway control into the brake controller, and the trailer plug into the sway control module. This will give you a proper 7-way connection throughout in order to keep your trailer on the road and operating correctly. I've attached an image below for you to illustrate the correct orientation.
What trips are you planning on taking these parts on? Will you be on mountainous terrain or off-road terrain at all?

Hey, Thanks for the great response. No mountainous terrain or off roading here. Just going mostly local camping. Really looking forward to trying my new system out. Next is breaks and bearings for this thing.
