Or any body know the name/type of connector for the pump grober has linked to, so i can do my own connection.
I believe this pump was used on the supercharged cars
Have you not tried the main dealers? Should be available pretty cheaply I’d have thought. They usually sell every pin and plastic connector for the wiring looms although they can be tricky to find the part numbers!
Looking at the picture of the water pump and the "wrong connector" looks like the plug is essentially an oblong moulding with two female spade type connectors for + and - pins. Once you have the pump you might be able to judge the size of the pins and make up suitable individual sheathed female spade connector leads taking into account the current rating of connectors and cabling you use?
