: In 1982, Chevy relied heavily on the High-Energy Ignition (HEI) distributor system. Look for the thick pink wire on your diagram that provides a full 12 volts directly to the "BAT" terminal on the distributor cap when the key is in the 'ON' position.
Chevrolet used a standardized color-coding system in the early 1980s. When scanning your physical wiring harness or looking at a schematic, these are the most common color rules you will encounter: 1982-chevy-truck-wiring-diagram
