I got an 87 toyota supra turbo, and after I've fixed my clutch line something went wrong and my speedometer went dead, so now I don't know how fast I am going. Please Help!!! I tried searching the wire but so far everything is in place.
It's a mechanical speedo, there are no fuses to blow.
Most likely, when you were doing the clutch you broke the cable. I think in the '87s it was a three piece cable. It's VERY common for them to break. You'll need to replace at least the section that's broken.
