You will need a high pressure t piece connection, you can get these from a hydroulic fittings
shop,,
Various fittings/adapters to suit your sensor,, I think the thread on the oil filter housing is m10x1mm,
I could only get a 1/8 t piece so had to mess about abit, couple of extra adapters, but if you could get a m10x1mm threaded t piece, I'd get that
Screw your m10 adapter into the filter housing, attach you t piece to that, then put your oil pressure sensor on the t piece, your left with one open port,,
If I was you, I'd be putting an oil pressure sensor in, not temputure
That's what on done on my 20vt
