Getting the Wheeling Fever

I have a 94 Runner with a 97 3.4 swapped in. The A/C does not work.

I suspect it has to do with the tachometer signal. The A/C amplifier uses the signal to shut off the A/C compressor when RPM is too low and too high (I think).

Now, we all know you have to do the tach mod to make the stock 3.0 tach work with the 3.4 motor. So logic tells me the different 3.4 tach signal also messes with the A/C control.

Can anyone confirm this? Has anyone found a fix?
