Sound system upgrade and 8-pin connectors disconnect

[Gxgn]

Hi, has any of you managed to disconnect the grey and brown 8-pin connectors under the dash/steering column from the audio unit? I’m trying, in vain, for a few days to disconnect these two connectors and it’s very difficult, I cannot see what I’m doing. Any tips how to make this work? Thanks

They are difficult. The clip you can see on the LH side of the plug.

I know, I’ve been trying to press it and pull the connector at the same time but no luck so far.
