EV6 / EV14 Injector Harness for Holley EFI

  • Sale
  • Regular price $129.95


We've filled the gap by offering injector sub-harnesses that work directly with your existing Holley EFI main harness, but with cleaner routing and laid out more specifically to your application.

Direct plug-and-play with injectors that have a standard EV6 / EV14 connector, including FID 1000's, FIC 540-1650cc, and many factory late model injectors including Gen IV LS, Gen III Hemi, Ford Modular and Ford Coyote. No chintzy adapters needed!

Jolt Systems injector harnesses are built with mindful injector spacing, specific to the intended application, so they route much more cleanly than the semi-universal harnesses from Holley.

Each lead has a permanent white-on-black heat shrink label at the front cylinder for each side.

Bank 1 - 1-3-5-7
