We have just what you're looking for. If you don't already have a 4 way plug on your 2020 Toyota Highlander, you'll need to start by installing one, since those provide the base connections needed to install a 7 way. For the 4 way plug you'll want to use the Curt # C76CR, which will tee into your driver and passenger side tail lights.

If you've already got the 4 way connector, you'll just need the 7 way which can be installed using the # ETBC7. The ETBC7 will plug into the 4 way and once you've made connections for the ground, 12v power and the reverse light circuit or auxiliary 12v power source, you'll have a working 7 way.

The ETBC7 is designed to work with wireless brake controllers like the Curt Echo Mobile # C51180, since they don't require any wiring to be run into the cabin of the vehicle. This is an ideal setup for vehicles that don't come with a vehicle adapter plug for a brake controller, and would be the easiest setup to install. The Curt Echo is controlled by your smart phone (iOS 8.0 or newer/Android 4.4 or newer are required) and provides you with proportional braking for your trailer.

We do have what you are needing, with a 7-way kit that does not have brake wire since you aren't going to be using electric trailer brakes, and only want the 12 volt power. What you can use is the following kit: - 7-Way RV Upgrade Kit #ETBC7L…

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…
