This is where I have to say I have no idea as the hydraulic units and harness for 01 and 03 have different part numbers, so the harness may not match the connector. You are also going from ABS 5.3 to ABS 5.7 as well by switching to the 2003 unit, which uses a different control unit and wheel speed sensors (by 2003, most functions were moved over to the CAN bus, so the cars had a different instrument panel that now served as the "hub" for the bus controller network).
