What a hassle it would be to create your own ignition harness. Holley
knows that, and that's why they offer a these pre-terminated ignition harnesses.
Connects directly to the ignition connector on the main harness. Finished
harnesses are available for a broad range of applications (HEI, GM LS1 or LS2,
Ford TFI, and more) as well as universal coil-on-plug harnesses and unterminated
ignition harnesses.
GM LS Engine Note: Don't see an injector harness for the LS? That's because
the Holley LS main harnesses connect directly to the crank sensor, cam sensor, and
the OE even and odd coil harnesses
