Connector Pigtails

Connector pigtail assemblies to replace original General Motors (GM) vehicle and engine wire harness sensor connectors. Genuine Original Equipment Manufacturer (OEM) connectors by manufacturers like Delphi, Molex, Yazaki, Bosch, Kostal, and more.

Our connector pigtail assemblies are GM color coded for direct replacement of popular electronic fuel injection EFI engine wire harnesses used on TBI, TPI, LT1, LT4, LS1, LS2, LS3, LS7, LS9, and other GM Vortec engines.

EFI Connection uses production crimp tooling to ensure terminal manufacturer crimp specifications.
