If your focus is on repairing or understanding automotive ECUs, "Ecus Datasheet 2.0" is the most likely resource you are seeking.
When powering up an ECU on a workbench using a downloaded pinout, use a bench power supply with adjustable current limiting. Set the limit to roughly 500mA. If there is a short circuit due to an incorrect diagram, the power supply will cut out before frying the board.
