Features
- All leads fully terminated and plug-and-play except for battery power / ground.

- Injector harnesses included are compatible with all main harnesses from Holley.
- Included injector harnesses are interchangeable between stage I and stage II injectors.
- Pre-configured to run eight stage II injectors fully sequential through J2B ecu connector

Ordering Guidelines
- If only one injector harness is needed, select "I already have one" for stage I, and make injector harness selection for stage II.
- If running two different styles of injector between stage I and stage II, select for stage I and stage II in the order they're listed in the dropdowns. For example, select "EV1" first, then "Denso (Bosch 210)" for stage II instead of the other way around.
