Fog lights can really help a European vehicle stand out in a crowd. They can also help your eyes find the roads in some dark or stormy conditions. This harness kit was designed to work with Jetta and Golf IV aftermarket fog lamps on models not equipped with OEM fog lights. Pre-crimped connectors plug into the factory switch and light harness. Includes relay, zip ties, connectors, ground wire, and hardware. This harness cuts down your time and difficulty of install by including the right lengths of wires, number of relays and connectors. We have a wide range of Ziza offerings for your fog light needs; housings, bulbs and even complete install kits!
