I am trying to fit an amplifier in the space where the Parrot kit goes. However, I am struggling to disconnect the 12v Outlet in order to remove the glove box. What am I missing?
Where does the power supply disconnect? Between the white and black plastic?
Is there a clip that needs to be moved ?

Black connector pulls out of the white part of the plug, there is a locking tab on the other side that needs squeezing in to remove it
