Question:
Hello, I am very interested in getting the correct hitch to haul my jetski, just one, not the dual set-up. I also have a pretty light weight aluminum John boat, only 14ft. I keep seeing it’s just popular with the bicyclists. I have a 2021 Kia Seltos. Your YouTube channel has been so helpful in preparing to install this and the wiring harness once I find the right products. Thank you for your time and recommendations.

Hey Heather, thanks for reaching out. We do have a custom fit hitch for the 2021 Kia Seltos. Here is what you will need:
- Curt Trailer Hitch Receiver - Custom Fit - Class I - 1-1/4" # C65FR
This will be a direct bolt-on fit for your Seltos. It has a 2,000 lb towing capacity so you'll be good for towing a small jetski or boat trailer. You'll also need a ball mount like part # e47DR which comes with a pre-torqued 2" ball. Just make sure both your trailers also use a 2" ball and you'll be good to go.
We also have a custom fit wiring harness for the 2021 Seltos, and for that you'll need part # C89KR. That will be a pretty straightforward wiring install. You plug in behind the taillights on each side then run a wire to the battery to power the converter module. Nothing crazy. You'll find the manufacturer instructions linked below.
I've also included a link to our install video for the # C65FR hitch on a 2021 Kia Seltos. I imagine you'll find that helpful.
What trailer will you be hauling the most? Do you know what size ball the coupler uses?

Thank you! That’s exactly what I needed to know. This kit will be a purchase for me, hopefully sooner than later. I am impressed with the YouTube channel and thank you for responding so quickly. My jetski and small John boat both use a 2in ball so this kit is perfect! I just like to be double sure before having to deal with returns and all that hassle. Most likely it will be the jetski I haul the most and furthest. Where I launch my John boat is only 1mi 1/2 away. I am looking forward to taking my jetski to diff beaches but those are minimum 1hr 30-45min away.
