Anyone knows how to stop their speedenometer from rotating? I did it on my 96' civic cx. The main wire has three small wires, two wires on both sides and one in the middle, I unpluged the main wire which have these three wires and the speedenometer stoped, the gas speedenometer works fine and so does the after market RPM. But there is one problem with unpluged this main wire. The engine check sign is on, due to unpluged this main wire. I know for sure that one of the three small wires is the right one for stop the speedenometer for rotatings, however, the other two wires, I am not sure what they are for, and I am worry that keep driving my car with the engine check sign on might cause me problems(according to the manual). I know, the engine sign is on, must be cause by one of the other two wire being unpluged. SO, ANYONE OF YOU OUTHERE HAD DONE IT B/4, KNOWS WHICH WIRE IS FOR THE SPEEDENOMETER, PLEASE LET ME KNOW, YOUR KNOWDEGE IS WELL APPRECIATED. THANKS...
