Trailer Wiring Harness for 2010 Mazda 3 Without LED Lights But Trailer Does

Question:

2010 Mazda 3, 5-door Hatch. My vehicle does not have LED lights but the trailer does so Im not sure which light harness I should get. The descriptions appear to indicate the vehicle lighting as the prime factor in choosing a harness.

You are correct that the wiring harness designation has to do with the vehicle lighting and not the trailer lighting. This has to do with the source power coming into the converter.

Since you don't have LED's in your 2010 Mazda 3, I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118420. This will connect perfectly with your car and will not have issue with a trailer that uses LED lights. I've attached a video of this installation to assist.
