Hi Jerrod; the correct wiring harness for your 2025 Hyundai Santa Fe HTRAC AWD is the Curt T-Connector Vehicle Wiring Harness # C29ZV you were looking at. This will plug into the connection points in your rear cargo area and then a hot lead will run up to your battery.

Do you already have a trailer hitch?

Yes. I have a physical hitch installed already. This wiring harness (C29ZV) looks like it connects inline of each brake light and you run wires between them. Also requires a power wire run up the length of the vehicle. The OEM harness just plugs into a single connector under the cargo space. Do you have something that works like the OEM harness (without running wires all over the undercarriage of the vehicle?

@Jerrod that is correct, it is a pretty standard 4-way that works with the Santa Fe with and without the tow package. You won't really have wires running all over underneath the vehicle but I understand preferring the simpler installation process. Curt has been working on one that fits the factory connector for quite a while but I have no idea when it will be released at this point. You can pre-order the # C48RV and wait to see when it comes out if you want. It will also require the use of an adapter # PK12716 for a 4-way. The only other option right now if is to use the OEM wiring harness.

@RobinH Thank You. That's what I was looking for. You mentioned that you 'have no idea when it will be released'. On the etrailer listing, it says Sept 9-10. Is that not true? Is that a reliable date?

@Jerrod I would have to follow up with Curt and see. That is likely our best guess and could be pushed back, it really isn't up to us. I feel like we have been waiting for this particular wiring harness forever so that is why I phrased it that way. Curt isn't around on the weekend but I can reach out and see if they have a better time frame this week.
