Quad Headlight Wiring Diagram - Relay Terminals 30/85/86/87 (Ford Probe)

This document is a hand-drawn/computer-illustrated wiring diagram titled 'Quad Headlight Wiring Diagram,' showing how to wire separate low beam and high beam headlight bulbs through an automotive relay. The diagram identifies three primary wires at the top: a Low Beam Positive Wire (shown in green), a Ground Wire (shown in black), and a High Beam Positive Wire (shown in red), each passing through inline connectors (drawn as blue blocks). An automotive relay is depicted with four labeled terminals: 86, 87, 85, and 30. Terminal 30 connects via a red wire to a 12V+ source (battery). A blue wire is labeled 'To Output Contact' and a yellow wire is labeled 'To Switch Contact.' Two headlight bulbs are drawn at the bottom, labeled Low Beam and High Beam, each with positive terminal markings and light output illustrated as yellow beams. A reader can learn the basic relay-based wiring approach for quad (four-lamp) headlight systems, including which relay pins receive battery power, switch signal, and output to the lamps, and how the low beam, high beam, and ground wires route to the bulbs. The document contains no year, make, model, part numbers, fuse ratings, or wire gauge specifications.
