Adapter Needed for Curt Echo Trailer Brake Controller On 2019 Lexus RX 350

Question:

I have a 2019 Lexus RX350 installed your 4-way trailer connector. My trailer is single axel with electric breaks. I like the Curt Echo Wireless Trailer Brake Controller - 1 to 2 Axles - Proportional. What adapter do you have to bridge the 4-way to 7-way connection? Thanks!

In order to install the Curt Echo Wireless Trailer Brake Controller part # C51180 on a 2019 Lexus RX 350 with 4-way trailer wiring harness you only need the Wireless Brake Controller Install Kit part # ETBC7L which is super easy to install. Simply attach the two 4-ways together, ground the white wire, then run the black power wire up to the battery in the engine bay and that's it. This is a great controller option due to not having to drill into the dash and not having to splice into any wires
