Holley EFI LS main harnesses have a map sensor connecter designed for use with an LS1/2 style map sensor. The 558-416 is an adapter harness that can be used to adapt any LS harness that uses a LS1/2 MAP sensor connection to a LS3 MAP, which is recommended for this manifold.

NOTE: The EFI versions of the LS HI-Ram intake manifold and fuel rail are designed to accept Bosch Style EV-1 or Magneti Marelli Pico fuel injectors. OE LS fuel injectors may not fit properly in the Hi-Ram EFI intake manifold fuel rail assembly. There is a kit available separately for the LS7 Hi-Ram EFI to allow the use of stock LS7 fuel injectors, P/N 300-230 (see below in the service parts section).
