Add a standard 4-way flat trailer connector to your 2017-2022 Kia Sportage without cutting or splicing the factory taillight wiring. This vehicle-specific powered harness uses OEM-compatible T-connectors and an integrated circuit-protected converter for dependable trailer lighting.
The Curt 56321 is engineered specifically for 2017-2022 Kia Sportage models. OEM-compatible connectors plug directly into the vehicle's taillight assemblies, allowing the harness to integrate with the factory wiring without cutting, splicing, or soldering.
