The extended length of this harness also allows you to locate your expensive ECU out of the weather and giving a cleaner look. With isolated ignition, injector, and fuel pump circuits, promoting longer life for the main relays. Many hours of design and testing with a focus on simplicity and longevity in the high vibration marine environment make this a problem solver.
