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. 

Opting for a set of coils gets you a set of eight genuine IGN-1A coils from Haltech.


  • Compatible with IGN-1A smart coils from all popular brands, including Holley, Haltech, FuelTech, AMP EFI, FireCore and others.
  • LSX style ignitor connections make harnesses compatible with most COP / CNP EFI harnesses
  • Tighter coil-to-coil spacing to work with the "thru-rod" style brackets commonly used for remote mounting
  • Connection leads are same length as our valve cover mount coil harness set, making them ideal for firewall or cowl mount applications.
  • Cylinder head ground runs through high power disconnect to connect to cylinder heads while keeping a clean and simple installation
  • Individually numbered coil leads

Relay Power Harness

IGN-1A coils have specific power and grounding requirements in order to hit full potential and to make maximum power. Our high current battery power harness with relay ensures just that with a guess-free installation.

Improper wiring of coils will cause poor performance and can destroy coils.

Harness kits ordered without power harness include mating connectors for high current power / ground connections. It is then the installer's responsibility to wire coils to sufficiently sized power source / relay, properly connect grounds, and to properly activate coil power.

Any warranty claims for damaged coils, whether coils were purchased from Jolt Systems or otherwise, in conjunction with harness kits shipped without power harness will be rejected. No exceptions.
