LH 2.2 to LH 2.4.2 conversion - RPM Signal 12 volt to 3

So this is probably not tooo complex of a question for someone who knows about this. I am thinking about converting an LH 2.2 car to LH 2.4.2 so I can use a 91 9000-T ECU in the car. I don't want to use the DI/APC though. I tried this ECU in my 93 900, it works in that car perfectly. The main question is this. the LH 2.4.2 uses a 3 volt output from the EZK or DI/APC where as the 2.2 uses a 12 volt output from the negative side of the coil. How would I get the 3 volt output?
