Holley EFI Ford Modular 2V & 4V Main Harness (For Smart Coils)
Holley EFI Part #: 558-113
Matt's Notes: Use this main harness to run a 1996-2004 4.6 2V or 4V with smart coils. In addition to this harness you will need an injector harness, the Holley smart coil sub-harness (part number 558-312), and the coils themselves (part number 558-312 for each).
This harness uses a lot of stock modular sensors, like the coolant temperature sensor and the manifold air temperature sensor. It is intended to use Holley EFI oil and fuel pressure sensors or similar. You do have the option to use Coyote-type knock sensors with this harness.
