95 240sx

My tachometer is completely wacked out. It does not read the proper RPM. I'll turn the car on and at idle it will bounce between 3k and 6k and continue to do so while I accelerate. Every once in a while it drops into range but eventaully resumes bouncing everywhere again. It's completely unpredictable. The speedometer also doesnt work but that's only because i have yet to change out the speed sensor to the US unit.

Is it bad wiring, or do I need a new dash cluster altogether?
