Whilst trying to remove the bulkhead panel for some new spark plugs, I bested the release/lock flange on the connector for the engine harness to the ECU. As such, it seems the harness/connector is currently stuck to the ECU.

Is there a fix or part replacement for this, or am I looking at a new engine harness?

Is there a way to get the connector off of ECU without the lever?
