We verify whether the Sorento has the factory tow package and confirm the correct vehicle-specific harness for its taillight and trim configuration. The negative battery connection is isolated as required before electrical work begins.

Tow-prepped models are opened at the factory connector near the driver-side rear bumper. On models without tow prep, both rear taillights are removed carefully and their factory connectors are separated without damaging the locking tabs.

The correct harness is seated fully in the factory connections. For taillight-connected systems, the left and right leads are routed behind the bumper with protected, controlled paths that keep the wiring away from sharp edges, heat, and moving parts.

The lighting converter is mounted on a protected flat surface and the ground is secured to clean vehicle metal. When the selected harness requires a dedicated power lead, the fused power wire is routed safely to the specified under-hood power source.

The 4-flat connector is routed to a protected, accessible position beside the hitch and all loose wiring is secured. Running lights, brake lights, both turn signals, and ground integrity are tested before the taillights, bumper-area covers, battery connection, and other removed components are restored.
