My tach won't work now. I bought that indiglos from bnoon and I can't get the tach to move when I hit the gas. The speedo works from what I can tell, and the temp, and gas work as well. I don't know if this is just a size thing or it's not sitting right, because the overlay is a little warped, and tomorrow I will try some double sided tape, and see if that works, but I din't know if it will. I have a pre 98 car and I don't know if there is a differance with years, and gauges, but can someone help me? My dash is in pieces and I will have to put it back the old way if I can't get it to work tonight.
