Hi!
I found two wire connectors in the engine compartment that are disconnected. Both are quite big ones, wrapped with black plastic bag or something.
One is at the left side, when you look at front of the car, and comes from the washer pump wiring harnes.
All plugs for the washer pumps are connected.
Second one was founded at right side of the engine compartment.
Red circles at the picture shows roughly the places where those unplugged connectors are.
Where should those two connectors go?
Sorry about bad english...
