Trailer Wiring Recommendation for 2025 Kia Carnival without Tow Package
Updated 10/30/2025 | Published 02/14/2025
Question:
I have a 2025 Kia Carnival, produced in April of 2024 therefore it does not have the plug and play wiring harness for towing lights. Can you give me an idea if and when etrailer might come up with a solution for putting at least a 4 wire plug on this vehicle? Thank you in advance.

Hey William, for your 2025 Kia Carnival that doesn't have the tow package you'd have to install a universal style 4-way like the Curt part # C59236 as we don't have a plug and play option. I would hope we eventually get a kit that installs inline with the taillight connectors but we don't have a timeline on if that will be available eventually.
