This arrangement is frequent in later model K6A engines. Below are key terminal assignments for the primary connectors: Connector C37 (60-Pin) Pin 1 (PNK): Fuel Injector No. 1 Pin 2 (PNK/BLK): Fuel Injector No. 2 Pin 31 (BLK/YEL): Ground for A/F Sensor Heater Pin 32 (PNK/BLU): Heater output of A/F Sensor Pin 35 (RED/YEL): Crankshaft Position (CKP) Sensor (–) Pin 40 (RED): Throttle Position Sensor (TPS) signal Pin 41 (GRN): Ground for Throttle Position Sensor Connector E23 (34-Pin) Pin 4 (WHT/RED): CAN-High communication line (for ABS/Control modules) Pin 5 (PPL/WHT): 12V Serial Communication (Data Link Connector) Universal 16-Pin + 8-Pin Wiring (Retrofit/Aftermarket) 1 Pin 2 (PNK/BLK): Fuel Injector No
