For your 2018 Mazda 3 Sedan with LED lights, I recommend the Tekonsha T-One Vehicle Wiring Harness # 118405. This custom harness is confirmed to fit your vehicle and will install by connecting directly to existing ports located behind the driver and passenger side tail lights (inside the trunk). Once these connections are made, you will just need to run the hot lead up to the Mazda's battery. This will provide you with a 4-Way connector to connect with and power a trailer's basic signal lights.

I have also attached the written installation instructions that you can review.
