I have purchased a set of fuel injectors. The needle hub is from the 110 hp TDI with VAG part number 028 130 201 S. It has a round connector, while my old injectors have a square connector. Does anyone know the ET number for the connector on the engine cable harness? I haven't been able to find it at VW. In the computer, I only ever see the square connectors. For your assistance, I am grateful.
