Hey, so it has been about 4 years since I have last been on here and touched my car since i have been overseas. I have used the search button and searched google for my answers but I have come up dry. I am currently trying to install a mechanical oil pressure gauge on my 09 Speed 3 and I do not have the sandwich plate and I plan on doing it without one. Where would I be able to tap into to install my gauge? Would I be able to just unscrew an oil alley bolt and plug it into there? This car is foreign to me since I haven't touched it in years!! Any help would be much appreciated!
