Default Tach driver needed for Aeromotive FPSC?

I have the Aeromotive 16302 fuel pump controller to run my A1000. It says in the instructions that vehicles with coil packs need a tach driver to get the signal. What are you guys using? The motor is a 5.3L LS motor with stock pcm.

What year is the PCM and do you have a tach hooked up currently?

It is a stock pcm in a 2004 Chevy Silverado with factory gauges.

Do you happen to have a pin layout for the PCM? If you can track down what pin sends the tach it's signal... just tap in to it for the Aeromotive. Shouldn't be too tough if you can find out what pin sends teh signal.

Thanks for the info. That one says Engine Speed Signal (Except HP2)

Is this a 12v signal?
