IMPORTANT INFORMATION

Always confirm the correct OEM part number, machine model, serial number, and connector configuration before ordering, as electrical connectors may vary in terminal count, keyway design, and wiring specification between machine variants. A damaged or corroded solenoid connector can result in intermittent electrical faults, poor solenoid operation, transmission errors, starting issues, or unexpected machine behaviour. When replacing the connector, it is recommended to inspect the wiring harness, terminals, seals, and associated solenoid for corrosion, damaged insulation, or loose connections to ensure long-term reliability and trouble-free operation.
