Why this part
Generic wiring solutions introduce compromise at every join. This harness is built specifically for the Holley HyperSpark system, so connector geometry, pin count and wire gauge are matched from the factory. At $104, it costs less than an hour of workshop labour and removes the fault-finding headaches that come with improvised adapters.
