    Do you mean the internal wiring diagram for the ECUs, Brandon?

    To be clear, I mean the wiring diagram for the vehicle, showing the outputs from the ECU to the rest of the car.

    Thank you so much! I am working on developing a piggy back. With my intake and exhaust work, the car is running lean on the bottom end.

    I wasn't able to find anything on this, Dominick. The WSM, wiring diagrams and diagnostic charts offer no clues.

    One general Motronic 2.7 ECU pinout that I have (not Ferrari specific) shows the Pin 39 as "unoccupied". On the 348, it is connected to ground.
