Automotive 5-Pin Relay Diagram - Terminals 30, 85, 86, 87 & 87A (NO/NC)

This document is a simple hand-drawn style diagram explaining the terminal layout and functions of a standard 5-pin automotive relay that has both normally-open (NO) and normally-closed (NC) output terminals. The diagram shows a relay box with two coil terminals on top: terminal 85, labeled 'Hot wire from switch,' and terminal 86, labeled 'GRD-' (ground). Text inside the box notes that terminals 85 and 86 can be swapped, meaning coil polarity is interchangeable. The bottom of the diagram shows the output (switched) terminals: terminal 30, labeled 'From Batt+ Through fuse,' which is the common power input; terminal 87A, labeled 'To Load+,' which the diagram identifies as the normally-closed (NC) contact; and terminal 87, identified as the normally-open (NO) contact. A reader can learn which relay pins receive switched trigger power, ground, fused battery power, and which pin feeds the load, as well as the NO/NC behavior of terminals 87 and 87A. The diagram is generic and not tied to any specific vehicle, year, or part number, though it was uploaded to a 1997 Ford Taurus gallery alongside Taurus-specific wiring references.
