When you set up you tach adapter, did you run a seperate wire for the tach output? The tach wire runs through or near your obd2 connector, so it may not be coming in where you think it is. Since you celica isn't obd2, the lack of this connector may be part of the problem.
I would just run a wire straight from the taco pin on the ecu to your tach signal input pin on your beams cluster if you haven't tried this already. Bypass the tach adapter.

yeah well bypassing the thing makes the tach not work....so you might understand why im all funfused at it lol...
