I recently installed aftermarket gauges to monitor both water and oil temps in my 1992 NSX. After starting cold, I've noticed that my oil temp gauge goes up first and corresponds with the OEM temp gauge (which I believe is water temp). I've also noticed my aftermarket water temp gauge takes much longer to go up, maybe 10-15 minutes. Did I plug the sensors into the wrong gauges? It seems like water should be heating up first and it's an easy fix, but I wanted to confirm with others first.
