    Where can I find an obd 2 wiring diagram for a GSR ECU 96-98? I need to know what pins one the ECU are for the primary o2 and the knock sensor are. Already have it swapped and running so i dont really want to buy a book this late in the game. if anyone knows please let me know.

    Thanks!
    Rick
