200TDi Oil Pressure Switch Thread?

[Paul in Sussex]

Hi all
I have bought an oil pressure gauge for my 1991 200TDI. It already has a tapping on the oil filter head for an oil light switch so I need an adapter in order to retain switch and also add oil pressure gauge sender. Does anyone know what thread it is? Demon Tweaks can't help.

Thanks in advance
Paul
