Our Fog lights and the low beams are both H11. What you can do is swap the harness connections by using either H11 extensions or HID kits as they have longer wires. So basically connect the low beam bulbs to the fog lights harness and the fog bulbs to the low beam harness. Allowing you to run the fog lights without the low beams.. Before getting started with wiring diagrams for fog lights without a relay, it is essential to have an idea of the electrical components of a fog light system. Generally, the electrical circuit for fog lights comprises of these components - Power Source (Battery or Main Power Source), Ignition Switch, Fog Light Bulb, Relay. It is important to.
Want to add a fog light to a 1951 MG TD that presumably didn't come with them. Have attached to pictures. One is the current wiring in the car. The other picture is the wiring schematic for a TD. The wiring schematic shows the fog light wired from the light to the fog light switch and then wired to the ignition switch/light switch hub.. Below is the wiring diagram. The button came with about 10 feet of cable, a relay, in line fuse and light bulb connections because it's for fog lights. I used the actual button and the green connection which had 4 wires coming out from it (2 Red, black and blue).
