EV1 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 Billet Atomizers, Precision 500lb, Siemens / Deka injectors and many others that use an EV1 style connector. 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 with the front cylinder number for its respective side of the engine. GM / Chryslers are labeled 1/2, Fords are labeled 1/5.

Compatible with Holley main harnesses for HP, Dominator & Terminator EFI.
