VDO oil pressure guage and switch?

Well, it looks like I can forget about adding any oil cooler, except maybe if I hook up one of the lines to this plug, if it isn’t covering any sort of relief valve:

That would leave one of the plate’s ports free for the second line and the other free for a threaded adapter suitable for a pressure guage or even for a T or Y fitting accomodating both the guage’s sender and a temperature sender.
Other than that, because both mount and pipe are in the way, I will only be able to mount this plate facing either left or right. In which case, mounting it left will keep the newly added devices away from Catalyst heat

wow thats a really crappy fitment.
I belive that plug goes straight down to the oil pump. It maybe the factory oil return for turbo blocks and plugged for N/A.
If you have a look in an ed or ef engine manual you may be able to get a pic of the inside of the oil pump so you can see if I am correct.

The pdf I’ve got is visually vague. Nevertheless, that plug plugs a gallery which is connected to the oil filter’s inlet. If I were to tap it for a coolant line, oil woul no longer get to the filter. I’m tempted, in any case, to unscrew that plug and then see what happens.
I didn’t think to replace that plug with some sort of equally-threaded bronze plug of which I could drill and tap it for accomodating a guage’s sender[quote=“evilhighway, post:20, topic:6764, full:true”]…It was just a cheap chinese one from ebay or ali express…[/quote]Mine is probably also one of those. I just don’t know it yet. The threads in that plate are cut pretty crude. Nothing I’ve ever seen done in any Japanese or any other quality castings
