Draw thru oil feed

Hi all, i want to fit my draw thru to my trick efe for a while, Roger upperton has ordered some high flow oil pump gears for me, he suggested removing the oil pressure switch and taking the feed for the turbo from there, I'm happy to do that, however i still want a working oil pressure light, any ideas?
I will just ren the drain to the clutch case cover
