New fuel pump T3 Kombi

I have just bought a new fuel pump for my T3 Kombi and the 2 electric fittings are different sizes [ screw on ] .This suggests to me that it should be wired a specific way. The old one had spade connectors [ identical ] and were not marked + or - . Any ideas? Thanks Wayne

They are marked - you just have to look REAL hard

There is a + & - sign there

I just did mine and finally found them

Will have a look under tomorrow if it dries out

Thanks Bizzare, you are right. cheers Wayne
