Question:

I have a 4 way on my vehicle now. I bought an Tent Trailer and it asks for a 7 way. Will this adapter be the only thing i need to have my tent trailer working properly? Including the electronic brakes that come equipped with my trailer??

You will need go with a different adapter to convert the 4-way of your 2015 Sienna to a 7-way and activate your trailer brakes.

So the easiest to install brake controller that also works really well is the Curt Echo Mobile part # C51180. Basically this just plugs into an active 7-way and once you sync it to your phone it's ready to go. This brake controller is proportional which means it senses the amount of deceleration your tow vehicle is applying and applies the trailer brakes in a relative way.

To convert the 4-way to a 7-way so that you can install the brake controller only requires the 7-way adapter kit part # ETBC7L. The 4-way of this plugs into the 4-way of your vehicle and once you run the included wiring and breaker up to the vehicle's positive battery post it's active enough to allow the Echo to function. This saves you from having to hardwire in a brake controller which requires tapping into the brake signal of your vehicle and running a few other wires too.
