2-Pin 0.6mm A/C Compressor / Solenoid Valve Wire Harness Connector – OEM MG644111 / MG644111-5
2-Pin 0.6mm A/C Compressor / Solenoid Valve Wire Harness Connector – OEM MG644111 / MG644111-5
Direct OEM-specification replacement for the 2-pin wire harness connector used on A/C compressor clutch coils and solenoid valves across multiple vehicle platforms. Cross-references OEM part numbers MG644111 and MG644111-5. Uses the 0.6mm contact series in black nylon housing — designed for A/C compressor clutch coil and variable displacement compressor solenoid valve applications where a compact, lightweight connector is required.
What Problem Does This Connector Solve?
The 2-pin A/C compressor connector is located on the compressor body in the engine bay, exposed to heat from the engine and A/C system, vibration from the compressor, and road spray. A failed connector causes the A/C compressor clutch to disengage or the variable displacement solenoid to lose control, resulting in no cold air from the A/C system. The 0.6mm terminal is extremely fine and susceptible to corrosion and mechanical damage during engine bay work. A failed compressor connector is frequently misdiagnosed as a refrigerant leak or compressor failure before the connector is inspected.

Frequently Asked Questions
Q: My A/C compressor clutch is not engaging and the refrigerant level is correct — could it be the connector?
A: Yes. A corroded or open 2-pin compressor clutch connector is a common cause of A/C compressor clutch failure. Test for 12V at the clutch coil connector when the A/C is switched on — if there is voltage but the clutch does not engage, the clutch coil has failed. If there is no voltage, inspect the connector and wiring before replacing the compressor.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
