I need to remove a single wire connector from the

this requires a special tool to release the the connector pin from the connector shell, u will have to buy that tool from the dealer, most likley it is a kit containing all the wiring terminal tools, u will need to inquire, no one else will have this tool., u will need to order it, u can also try using a flatinned paper clip to release the tiny spring out retainers that fold the terminal into the connector shell, be careful, if u damage the connector shell u have really created a mess for yourself.

Hi,
Removing a wire from the connector can be a pain, but is not impossible with a decent pick or two.
Each connector has a retaining clasp pushed into it, either a large rectangular panel across the top/broad side of the connector, or a flat wedge pushed into the end of the connector. This locks all the pins in place to prevent accidental removal.
According to the factory service manual, the MT/ECU connector has the wedge retainer pushed into the end.
Remove it using a steel pick to unlock the wire terminals.
Then using a straight pick release the plastic tab holding the wire terminal in position while appplying light pressure pulling rearward to slide the wire out.

I have linked a picture from the factory service manual to help out.

If you have any questions or need clarification, please ask so that I can help you further if necessary.
