4-Pack Used GM Delphi Relay 15328866 (8866) - For Chevy Silverado, Tahoe, Avalanche & More

This is a pack of FOUR used GM Delphi relays, part number 15328866 (often just called 8866). They're 4-pin relays commonly found in Chevy Silverado, Tahoe, Avalanche, and other GM vehicles. Condition is used – they've been pulled from working vehicles, so they may have cosmetic wear but should function properly. Great for diagnosing electrical issues, keeping as spares, or replacing faulty relays for things like fuel pumps, fans, or lights. Much cheaper than buying new, and OEM Delphi quality. If you're a DIY mechanic or just want to have backups for common failures, this 4-pack is a smart buy. Test them when you get them to ensure they click!
