A complete, LS Based, sub-harness for the Holley Smart Coils, IGN 1-A Coils, and AEM/Mercury Marine Coils. Produced with over-sized 16awg CrossLink Wire for all individual power and ground connections and 12awg CrossLink Wire powering each bank, this harness will create peak-power spark, and never compromise your wiring harness or ECU. Easily removable with stock/Holley style 7-pin coil connectors, and a heavy duty Delphi/APTIV quick connect on the power supply. You will most certainly run out of coil strength long before any stress is put on the circuitry, and Holley Smart coils/IGN 1-A coils have been proven over 3,000hp.
