VX Tuning makes it easy to wire the fog lights of your new E-Code, GLX headlights , or any other aftermarket headlight with fog light feature. Everything needed to complete an OE quality installation is included in this harness. Pre-crimped connectors plug directly into the factory switch and light harness. No spliced or tapped wires and no special tools required. All bare connections are weather proofed with shrink tubing. Kit works on all Jetta and Golf IV’s not originally equipped with OE fog lights.
