Have you even tried it yet? I'm using the signal sent to my dash to run my NOS progressive controller window switch option and it works fine.

The only thing you will have to do is verify the "cylinder" setting on the tach results in the proper RPM output. A V6 setting may not work if the tach is expecting to see a specific voltage range... but I believe the PCM output should be correct.
The PCM has a different wave length pulse then what my tach can read, My tach reads from 4 to 6 to 8 cyl engines but since there is no converter for the pulse rate, i need to get a tach adapter; http://www.autozone.com/gauges-and-gaug ... 373324_0_0 ; but in simple terms, i need to get the tach signal directly from the coil packs.
