Fog Light Relay Wiring Diagram - Battery, Relay 85/86/87 & Switch Hookup

This document is a hand-drawn (computer-sketched) wiring diagram titled "Fog Lights," showing how to wire aftermarket fog lamps using a standard automotive relay and a dash switch. Two fog lights are drawn at the top, each with negative and positive terminals. The battery supplies power, with its positive terminal feeding relay terminal 87, which then routes power to the fog lamps when the relay closes. The relay is labeled with standard DIN terminal numbers: 86 (top), 31/51 (left), 87 (right), and 85 (bottom), with terminal 85 connected to a chassis ground symbol. A three-terminal switch labeled "Switch" is mounted "Inside Car" and its terminals are labeled POW (power), ACC (accessory), and GRD (ground). One fog light circuit shows a lead ending in a ground/pigtail connection on the right side. A reader can learn the basic relay-based fog light wiring concept: switched low-current control of the relay coil from inside the cabin, with the relay handling the high-current battery feed to the lamps. The diagram contains no wire colors, fuse ratings, gauge specifications, part numbers, or vehicle-specific applicability information; it is a generic universal fog light relay wiring schematic uploaded to a 1998 Ford Taurus gallery.
