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.
