My business partner has a2016 insignia SRI with the 2.0 CTDI engine and it has a water pump which has a blue connector for a plug. The water pump has failed and the only ones I can find come without the wiring connector. The part number is QCP3982 and this is the same as the old correct one. It even matches up the one without the connector with the number plate. I’m a bit stumped! Thank you
