Can anyone tell me where the Instrument Interface Module is located?

I'm trying to diagnose an electric problem w/ my O/D switch and shift interlock. First step is to unplug the connector to the Instrument Interface Module, but the service manual isn't telling me where to find it! Any guidance is greatly appreciated.


'95 Contour GL, Zetec/ATX

Repairs: * wheel bearings * sway bar stop * left CV joint * alternator * shift interlock *heater tube * VSS *tensioner *
Why do I still love it?
