I don't wanna open a new thread, so I'll reuse this one to post a few questions before I get on to installing an oil cooler. All of the parts arrived so I just wanna make sure I got everything conceptualized as I should, so I have several questions (some of which are pretty simple and maybe stupid, but bear with me pls).

1. Does the oil cooler have a direction how it's supposed to be turned? I'm guessing it doesn't.

I bought the thermostatic plate adapter.

2. The side with the rubber, I'm guessing goes toward the engine, correct? The other side is flat, so the oil filter should attach on that side, yes?
3. On the thermostatic plate, the black hex screw is probably factory sealing the thermostat, nothing to do there, correct?
4. Thermostat itself is now probably closed, as the temperature isn't hot. But when I look through it - I can see the path for oil is partially open. Is this by design? I thought it would be completely closed until a certain temperature, and open only then to let the flow get to the oil cooler. Do I misunderstand something here?
5. These fittings on the sandwich plate and the same fittings on the oil cooler - should I use teflon or threadlocker or any other stuff to make sure it's tight and doesn't leak?

This is the pressure sensor and I just places the T-fitting on top of it to check threading. Here I have the following issue:

6. The thread on the sensor is for whatever reason, cone-shaped. It literally expands just a slightly bit going from top to bottom. It's barely visible, but you feel it the moment you start threading the T-fitting. Threads are 100% same width. Is this normal or is this a manufacturer's defect? I can imagine it being deliberate, so to have better thread engagement to get a super snug fit, but I'm worried the T-fitting might break if I thread it fully. I would sandpaper the bottom part of the threads so they fit easier, because it will be snug anyway, and I'd teflon or threadlock there. Thoughts?

Last question is regarding wiring. I know just the basics about wiring so I'd like to reconfirm something that's probably very obvious....
This is the schematics I got with the pressure gauge

7. I want to have amber-amber lighting, which is described as ignoring the WHITE wire, and connecting only the ORANGE to the battery. BLACK and RED being the + and - wires, naturally. Am I right to assume that I need to tie both ORANGE and RED to the + terminal of the battery, BLACK to the ground and that's it? Wouldn't that inevitably drain the battery? I suspect I should connect it to something that turns on with the car....

Thank you!
