Ok, I've tried the search for the last hour and haven't come up with anything difinitive. I'm having problems with my speedometer and tach. They just won't work. As far as the tach I've read stuff about checking the TFI module and other things, but where is the best place to start? And the speedo? The speedometer cable is in two pieces with a controller for the old cruise controll in between. Whats the best way to check this piece to see if it's the problem?
