Viscous Fan Electronic Wiring Harness for Ford New Holland TM and Case MXM Series Tractors SKU: QT44222

When your tractor starts overheating because the viscous fan won't engage, the problem often lies in the wiring harness, not the fan itself. This replacement wiring loom for Ford New Holland TM and Case MXM series tractors restores proper communication between your engine computer and viscous fan clutch, preventing costly overheating damage and keeping you productive in the field.

Why This Electronic Control Harness Matters

• Each wire is properly sized for its electrical load, preventing voltage drop that causes erratic fan operation
• Heat-resistant insulation that survives the extreme temperatures near modern turbocharged engines
• Sealed weather-pack connectors keep moisture out - critical when washing down equipment or operating in humid conditions
• The loom covering protects against abrasion from vibration and contact with other components

This electronic control harness handles the sophisticated demands of modern 100-180 horsepower tractors running heavy implements and PTO equipment all day. For fitment questions or technical support, call S&H Parts - we've been helping customers solve electrical problems since 1969.
