Off-Road Light Bar Wiring Diagram - 4 Lights, 4 Relays, Switch & Battery

This is a simple hand-drawn (computer paint style) wiring diagram showing how to wire a light bar with four lights using four relays, a switch, and the vehicle battery. The diagram uses color-coded lines: magenta wires run from each of the four relays up to the four lights on the light bar; red wires connect the relays to a single switch and also run from the battery positive terminal to the relays/switch circuit; black lines represent the ground/negative path from the battery around the perimeter of the circuit to the lights and relays. Only four text labels appear on the diagram: 'lights' (pointing at the four round lamp symbols along the top bar), 'Relays' (pointing at the row of four square relay symbols), 'Battery' (labeling the large rectangle at lower right), and 'Switch' (labeling the square at lower left). No wire gauges, fuse ratings, relay pin numbers (85/86/87/30), part numbers, or vehicle-specific information is given. A reader can learn the general topology: one relay per light, all relay coils triggered by one dash switch, with power sourced from the battery and a common ground loop. It was uploaded to a 1993 Ford Bronco gallery but the diagram itself is generic and not vehicle-specific.
