Correct Wiring Harness for 2010 Mazda CX-7 Without Tow Package

Question:

I have a base model CX7 sv. It does not have an optional towing package, however it does have the female port on the passenger side of the car as shown in your video for part C55593. Is this port now standard? I was looking at part 118405 until I looked at the car out of curiosity. Not sure which one to get. Thanks

According to one of our friends at Curt although your CX-7 has the port on the passenger side, using part # C55593 would not provide all the lighting necessary for your trailer. Not all of the wiring connections were made.

For your CX-7, part # 118405 would be the correct wiring harness to use. The T-1 would connect inline with the existing wiring behind each tail light assembly. A wire also needs to be ran under the vehicle to the engine compartment ultimately connecting to the positive battery terminal.

I will provide a link below to the installation instructions.
