Answer: This is often caused by brittle insulation or cracked connectors in the 6754-81-9520 harness. High engine temperatures cause standard wires to harden over time. Inspect the harness for signs of melting or corrosion at the plug terminals.
Answer: Ensure all mounting clips are secure to prevent vibration-induced wire fatigue. Always use the correct 6754819520 part number to avoid tension on the connectors during installation.
