MK7 Jetta Headlight Extension Harness (14 Pin to 14 Pin)

This harness extends the factory 14 pin headlight wiring by approximately 12 inches (30 cm), providing the additional length required when upgrading from Basis LED to High LED headlights.

The harness is a direct 14 pin extension and retains the factory pin configuration without changing the wiring or headlight functions.

Why This Harness?

When converting from Basis LED to High LED headlights, the original 14 pin headlight wiring may not provide enough length to reach the connector location on the replacement headlight assembly.

This extension provides approximately 12 inches (30 cm) of additional length for proper routing and a strain free connection while keeping the factory wiring intact.
