Custom MerCruiser Style Engine Harness

These harnesses were designed to be used in custom engine installations. If you've ever tried to use an original Mercury harness on a custom engine install you know that all of the wires either aren't located where you need them, or they're short or long. And there's so many you end up not using. Thankfully Hardin Marine stepped in to build both a custom harness and a do-it-yourself harness using a factory Mercury style engine plug. Don't suffer from a tangled spaghetti nightmare of wire. Both the custom and universal harnesses are engineered of the highest quality wire, connections, terminals, and components. These systems do not have buzzer capabilities.
