Ordered a hitch and the "custom" wire harness from eTrailer. Had installed their equipment on three previous cars. Hitch was a bit of work but not more than expected. THEN I discovered the wire harness was really a universal harness that would require splicing into the various 22ga brake and turn light systems. This is an additional problem with all the electronics in the rear of the CX-30. There is not sufficient room to access the wires and I was afraid of cutting the small wires due to lack of space as seen in the attached. Auto part Vehicle Car Engine Wheel
Has anyone discovered a company that offers a wire harness that can be installed by simply un-plugging the OE connector and plugging in new connectors as seen with most of the eTrailer wire kits?

I ordered the Curt Hitch and Wiring harness, harness part number 56450, going to install it this weekend, I can let you know how it goes... it's a harness made for it, direct plug n' play - no splicing.

I did install the Curt 56450 light kit and the trailer lights were not flashing correctly. Confirmed it was not the trailer by using a test plug. ETrailer replaced it with the Tekonsha light kit and it works fine. Perhaps I just got a defective kit? As you know the harness just plugs into the existing sockets and most of the work will be in running the 12 volt wire up to the battery. I wasn't too keen about running it on the bottom of the car so I ran it on the inside under the front & rear door kick plates then through a rubber boot in the firewall.
Let us know how the Curt kit works for you
