Recommended Wiring Harness for a 2025 Kia Carnival Hybrid
Updated 10/30/2025 | Published 02/18/2025 >
Question:
I have a Kia Carnival HYBRID, model SX Prestige. I am looking for a wiring harness for a trailer. The unit I have found on your website indicates it has not been confirmed to fit the HYBRID version of the new Carnival. Any idea when it might be available? Is there a way I can place my contact info to be notified when a suitable harness is available? Thank you

Hey Gary! I checked with all of our vendors and no one has a plug and play wiring harness for the hybrid model of the 2024 Kia Carnival. Additionally, none of them had an eta on when to expect one.
The only option I have for you is to install the ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit item # 119250KIT. This is a universal wiring harness that clamps onto your Kia's tail light wires. It mimics the signal sent to them and activates the corresponding functions on the 4-way.
If you have any additional questions feel free to reach out in the comment box below and I'll be happy to help you.
