HARNESS EXTENSION SUZUKI 5M 36620-93J02

Function and technical context

The 36620-93J02 harness extension is part of the electrical control system of the Power Trim in Suzuki outboard engines, allowing the wiring route between the control unit and the trim motor and/or the management unit to be lengthened. It works within the power and signal circuit of the hydraulic trim system, guaranteeing the correct transmission of electrical commands to tilt and adjust the angle of the engine according to navigation conditions. A deteriorated harness, with rusty connectors or conductors damaged by marine humidity can cause intermittent or total failures in the operation of the trim, making it impossible to regulate the angle of attack of the engine and directly affecting the performance and maneuverability of the boat. At 5 meters in length, this extension is especially useful in installations where the distance between the control console and the engine requires a greater wiring reach.

When to replace this part?

The most common symptoms of a bad trim harness include erratic operation or no response of the trim when pressing the button, trim indicators that show incorrect readings on the instrument panel, or short circuits that activate protection fuses repeatedly. In marine environments, corrosion of terminals and cracking of wiring insulation due to prolonged exposure to the elements are the most common causes of failure; It is recommended to inspect the condition of the harness during each seasonal maintenance and replace it if there is any sign of visible deterioration. Acting preventively avoids being left without trim control during navigation, which can compromise the safety and performance of the propulsion assembly.
