• Plug-and-play HyperSpark support in the main harness: The harness includes built-in compatibility for HyperSpark distributor timing control, reducing setup hassles.
• Adapters for other ignition types available: Optional adapters (sold separately) broaden compatibility with different ignition configurations.
