As the title reads, the oil pressure light will flicker when:
- Sitting at specific red lights (maybe a certain angle causes this?)
- Rarely when going over speed bumps
- Getting close to stalling
- Driving like a fool (I don't push the car like this anymore)
I ran through several forum posts from years ago and found some great info for my issue, it's good to know some other people have had the same problem. I have read that it could be caused by the oil pressure switch shorting out, but I'm really no good with electronics (I can solder pretty well, but I have never had time to learn or understand circuits). Even with my multimeter, I am not totally sure what I am looking for or even how to start testing, let alone how to mimic the conditions that cause the light to flash. For context, this has been an issue ever since I got the car, but I never really thought anything of it because the car runs very well. I want to work this little problem out because I am now going to be making a much further commute everyday and I'd like to work out all my little issues.
My best guesses for the problem are electrical issues (the person I bought the car from is a "handyman" if you know what I mean), potentially an old oil pressure switch, or maybe even an old oil pump.
My thoughts for the solution are getting a new oil pressure switch and installing an oil pressure gauge. I have always wanted to put a pressure gauge in and I figured now was the perfect time. To make the pressure gauge work, I was planning on getting a 1/8 BSP (male) to 1/8 NPT (female) adaptor and a 1/8 NPT Tee-fitting so that I could use an electronic pressure sensor and still have the oil pressure switch (I hate lights on the dash).
Does this sound reasonable? If yes, any ideas for poking through the firewall? I don't want to drill through it... I'm also looking for advice on wiring for the gauge. I was planning on getting a Glowshift gauge kit.

All the fittings I was looking at are stainless steel from McMaster.
