Having some really strange issues in my old civic. Removed my old boost/oil temp/oil press gauges to fit some different ones. New ones dont work...Now old ones dont work. All they have is a small wiring harness...12v constant, 12v switched and an earth. I have tested all with a multimeter and they all produce what they should. WTAF?! How can 3 new gauges not work plus 3 old ones. wtf is going on?! So weird.
