For Crankshaft Position (CKP) and Camshaft Position (CMP) sensors, use shielded cables to avoid electromagnetic interference.
Connected in a one-to-one correspondence with specific ECU nozzle signals.
Measures how far the driver has pressed the accelerator pedal. Found on older models for scanning basic diagnostic codes
The K6A is notorious for needing strong grounds. Ensure all ECU ground pins are connected directly to the engine block or battery.
