The distributor mechanic disassembled various parts in the driver's side engine bay at the top in a tunnel between the fire wall and the windshield, isolating the electrical wiring running through the tunnel, checking for water corrosion in the contacts or connectors and put this "plug" attached to the entrance wall of the tunnel whose cables come from the fuse box, I suppose.
I did not find this TSB that gave more details.

The point is that the noise that was heard as "air being drawn through a half-open window" on the dashboard on the driver's side when driving at 80 km / hr, disappeared completely.
