EV6 / EV14 Injector Harness Compatible with Holley EFI

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 use a standardized EV6 / EV14 connector, also known as USCAR. Including but not limited to:

• FID 1000's
• FIC 540 - 1650cc
• Injector Dynamics ID1050's - ID2600's
• Most factory late model injectors including Gen IV LS, Gen III Hemi / Hellcat, Ford Modular, Coyote and Godzilla.

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.

• Built 100% in-house, in the USA.
• Genuine components used throughout.
• Black injector connectors offer a cleaner and more subtle look than the gray.
• Compatible with Holley main harnesses for HP, Dominator & Terminator EFI.
• Compare to Holley P/N's 558-201, 558-210, 558-212.

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