Trailer Wiring Harness Needed to Add 7-Way Connector to 2019 Toyota Highlander
Question:
I did check the Echo but I dont have a phone that would work with it. I just want to know if I can install a 7 wire harness the old fashion way even though the Highlander has LED break lights . Thanks.

When it comes to supplying power to the brake lights to your trailer your 2019 Toyota Highlander actually has an existing connector so you don't have to splice into the OEM wiring on your vehicle. To add a 4-Way connector for your basic trailer lights you either need the T-Connector Kit # 56042 if you have the factory tow package or the T-Connector Kit # C56217 if you don't have the factory tow package.
If you're referring to controlling the brakes on your trailer then you will actually need a brake controller for that. A brake controller will pull power from your vehicle battery as the brake light circuit on any given vehicle doesn't offer enough power to activate the brakes. It looks like you were checking out the Curt Echo Brake Controller # C51180 (which is an excellent choice) so in order to utilize this brake controller you'll need to install the 7-Way RV Upgrade Kit # ETBC7L. This it connects to the 4-Way connector mentioned above and then comes with a wire and connections to supply 12V of power to the Echo which, in turn, communicates with your trailer brakes and adjusts them depending on what settings you choose. The only other thing you'll want to get is a mounting bracket like part # 18136 which helps make your installation look clean.
I have attached some installation videos that you can check out on a 2019 Highlander so you get a great idea of what all of this entails.
