90 Civic Si, OBD1 Mini-Me Z6. Ever since I did my Mini-Me swap the oil pressure light in the dash didn't work. I even put the OBD0 ECU back in and it didn't work. So today with normal city driving all of the sudden it came on. It didn't sound any different and it seemed as happy as can be. My dad quickly drove it into a parking lot and I checked the oil in the crankcase and its right up to the full line. Then I took off the oil fill cap while running and oil spat out and it looked well lubricated in there. Then we shut it off and went for dinner for 45 mins. We came back and fired it up and no light. It doesn't come on when the ignition is set to "on" too there is just no light at all. The only thing I can think of is my wiring. What do you think?
