Wiring diag help: what do tach and coolant temp have

in common? I have a CEL for intermittent random misfire and the engine runs rough. The freeze frame shows tach going to 0 and coolant temp going to -40 momentarily. I think this means a power or ground interuption to either the 5V supply to these or on the ECU. Is there any place in the wiring diagram that would lead to where to look?
Where is the ground for the ECU?
Thanks.
