How do you remove wire harness from ecu?

To remove a wire harness from an ECU (Electronic Control Unit), first ensure the vehicle's ignition is off and disconnect the battery to prevent electrical shorts. Locate the locking mechanism or clip securing the harness to the ECU and gently release it; this may require pressing a tab or lifting a lever. Once the lock is disengaged, carefully pull the harness straight out from the ECU, avoiding any twisting or bending that could damage the pins. Always consult the vehicle's service manual for specific instructions related to your model.
