Easy to Install Brake Controller Recommendation for 2020 Toyota Highlander with 4-Way

Question:

I just got a 2020 Highlander with the factory tow package. I’m unsure if the existing 4-port wiring will control the trailer’s brakes or just the lights. Do I need to buy and install a separate brake controller? The mechanic at my dealer thought no, but the RV place where I bought my trailer said yes. Thank you!

The 4-way trailer wiring you have now will not control trailer brakes as that type of connector only covers the basic turn signals, stoplights, and running lights. To control trailer brakes you'd need to convert that to a 7-way and install a brake controller to actuate the trailer's electric 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 # ETBC7. The 4-way of this plugs into the 4-way of your vehicle and once you run the included wiring and 30 amp 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.
