94-95 Mustang 5.0 AODE MS3 Gold Box w/ Microsquirt

Looking back at the OD Switch setup. I have an available mosfet that I could utilize.

Instead or rewiring the switch itself to ground and losing the illumination of the switch I am thinking that I can wire the trigger from the harness pin 10 to the mosfet and have it ground pin 34 on the micro.

Sound like that will work?
 
Update on this project. Steve and I did get this setup working and functioning the 2 speed fan, A/C idle up, A/C WOT Cut, and most importantly the AODE. I did end up getting rid of the Gold box because I was not impressed with the packaging and how it had to be installed in the car.

I have since went to a PimpXShift and am much happier with how the setup is on the car. So much cleaner.
