Trailer Wiring that Works with EcoHitch for 2021 Subaru WRX

Question

Question:

Hello, I have a 2021 WRX. Im looking at getting the Ecohitch 306-X7257. Is #C56259 the correct wiring kit Id need, will the trailer wiring connect to my car as is? I am looking at getting the harbour freight 40x48 trailer. What other parts would I need to connect this trailer to my car. Would the trailer attach directly to the Ecohitch, or is another part needed to connect the two?

The Curt trailer wiring harness part # C56259 is the correct fit for your 2021 Subaru WRX and would work great with the EcoHitch part # 306-X7257 which is also a fit. It installs by plugging inline with the taillight connectors of your vehicle. You will also need a ball mount like the # 3371803307 which comes with a 2 inch ball and a pin and clip and you'd be set.
