help needed to unpin wire

[ber075]

Hello,
I am unable to unpin wire on a connector.
I don't know the process? I have tried with a screwdriver and with pin kit, but I don"t know how to process and the wire stay plugged?
Could you help?

The second photo shows the secondary locking tab/bar - the centre piece that has the green marker on part of it. Lever this up first and then release the primary locking tab of the individual pin by inserting your tool from the front side and gently prying up while pulling the pin out the back.
