For many applications, such as in European Lada models, the 81-pin connector follows this general structure for critical functions: Pin Number(s) Description 12, 13, 44 Permanent battery power and main relay output Ignition Switch (+12V) Terminal 15 ignition signal Ground (GND) Chassis ground connections K-Line Communication Standard diagnostic communication line Ignition Coils 1, 2, 4, 5 Control signals for ignition events Fuel Injectors Direct control of injector pulsing Sensors (Inputs) 15, 26, 42 Coolant temp (15/26), Crankshaft position (42) Specialized Connection Guides 0 PIAGGIO
