well while im waiting for the rest of the car to get painted. here is how i got the celica Tach to work with the V6 signal

in my purchase of the 1MZ i got the gauge cluster too. i have a spare celica cluster so i took a chance on doing this mod. I think i read on MR2oc.com that this is the easiest way to do it.

first take the clear plastics off both gauges. first the celica gauge then the camry gauge.

flip the gauge over and under the tech you will see some screws. remove all of them to free the tach.

this is the backside of the tachs. 

carefully move the needle to the 6 oclock position and then pull off the needles. 

on the camry gauge you remove the 2 screws on the front and it will free the circuit card. on the celica gauge you have to carefully pull the face plate off, then remove the 2 screws. 

all you have to do now is switch them around and put back together. This should give you a calibrated tach for the signals coming off the V6 instead of an I4.
