Adapters & Harnesses

Adapters and harnesses help connect upgraded lighting components to compatible factory wiring. FKASTOCK carries application-specific solutions for select facelift conversions, regional lighting conversions, and other electrical upgrades. Compatibility can depend on the original lamp type, connector pinout, vehicle generation, market specification, and installed modules. An adapter does not guarantee plug-and-play operation in every application; coding or wiring changes may still be required.
