My car came from factory with standard gauges. I bought the car and it had the rally gauges installed. When I removed the gauges to see what had been done. I noticed some wires attached to the tach and some wires hanging. There is a grey wire hanging that I am not sure if it's for tach or something else. I have read that it would be a gray wire for tach but this car came with standard dash. I don't know if harness has been changed or if it goes elsewhere. Some other wires are going to tach. I thought that it would be blank. Look at the pics and see if you guys can tell me something thanks.
