Making the switch to smart coils on your Ford Mod Motor or Coyote, but already have Holley EFI? Our Mod Motor specific kit makes a hassle-free transition from the stock Ford 2 pin coils.
This harness kit is intended for use with Holley EFI main engine harnesses that originally used a pair of driver modules for factory "dumb" coils, including but not limited to Holley part no's:
- 558-108
- 558-109
- 558-110
- 558-506
- 558-507
If you have a mod motor or Coyote harness that was intended for use with smart coils, see our standard universal IGN-1A coil harness kit.
Smart coils are an excellent choice for ignition on high compression / high boost race cars, but have very specific power and grounding requirements to hit their full spark potential. Our complete harness kit allows for just that with a simple plug-and-play installation. Our smart coil wiring kit is also one of the cleanest, best-finished and most inclusive kits available.
