Fog & Spot Lights, After-market

Note: The in-line fuses prevent faults in added wiring damaging the original harness, they should be connected as close as possible to where the red and brown are picked up. More recent systems tend to switch the earth to the lights, which means they are permanently connected to a fused 12v supply. This is no safer than as shown above but does require extra wiring as both 12v and earth wiring is required to the lamps, relays and illuminated switches.
