Our HyperSpark kits were designed to make upgrading your ignition on a Sniper 1 EFI equipped engine simple. When installed along with a Sniper 1 EFI system, the combination creates the easiest conversion to install on the market, with only four connections required. Our harness only requires one connection to a switched 12V, battery+, battery-, and fuel pump power. The pre-terminated connectors and a built-in 40A relay provide power to all of the components within the system. With the main harness included, you no longer need to run multiple wires to provide switched 12V for each individual component. Route the harness and pre-terminated connectors to your HyperSpark coil, distributor, and ignition box and plug them in.
