3-Pin 6.8mm Engine Cooling Fan / Fuse Box Connector OEM 1544226-1 / 1544225-1 / 1544225-3 / 1544226-3 – Peugeot / Citroen
Direct OEM-specification replacement for the TE Connectivity 3-pin 6.8mm high-current connector used on engine cooling fan motor harnesses and fuse box circuits across Peugeot and Citroen (PSA Group) platforms. Cross-references TE Connectivity OEM numbers 1544226-1, 1544225-1, 1544225-3, and 1544226-3. The 6.8mm pitch is a high-current terminal series — used for cooling fan motor power circuits that draw 15–30A. A heat-damaged or corroded connector at this current level causes intermittent fan operation, engine overheating, and P0480/P0481 cooling fan relay faults.

Q: My Peugeot engine is overheating but the fan motor tests OK — could it be the connector?
A: Yes. A corroded 3-pin 6.8mm connector is a common cause of cooling fan failure on Peugeot/Citroen even when the fan motor itself is functional. At 15–30A, even minor corrosion creates significant voltage drop across the connector, reducing fan speed or preventing operation entirely. Measure voltage at the fan motor terminals with the connector plugged in — less than 11V under load indicates connector resistance.
Q: What is the difference between the -1 and -3 variants?
A: The “-1” suffix (black housing) is the original design; the “-3” suffix (green housing) is an updated revision with minor dimensional refinements. Both are functionally interchangeable for the same circuit position. The green color on the -3 variant follows PSA’s color-coding convention for updated harness components.
Q: Are terminals included?
A: Yes, 6.8mm high-current terminals are included with all variants.
