Does anyone know how to hookup a tach to an 03 cobra with a ford computer?

I designed my own circuit box that uses the crank trigger signal and puts out a tach signal. But on some ECMs, I believe that it is possible to get a tach signal as one of the outputs. I never did find it on the Mark VIII ecm but the Mustang ECM is slightly different.

I've got an '01 4.6 cobra computer running the engine. Do you know how to test to find the wire with the tach signal?
