Circled is the electrical ground box mentioned earlier. The cables running to it are in the way of the motor mount, so it has to get sung out of the way along with the washer reservoir. The arrow points to the single nut (10mm) that holds it in place. That nut/bolt is the connection to ground for a bunch of RF circuits -- headlight, fog light, parking light, ride height sensor, leveling control for the headlights if your car is equipped. Be sure to inspect, reconnect, & test before button-up.
