You can then click on the car model and it will pull up the diagram. But for the car it is not descriptive as to where it is.
On a 123.123 it is on page, 54 electrical equipment and instruments, then 045 fusebox and relay. Item number 47. But I don't know if the diagram is helpful for finding it in the car.

Second to find item in the car. Your "interval wiper control". Go to the service manual. Open it to the Electrical Troubleshooting Manual. Then open the "Wiring Diagram" section. At the bottom of the page is a blue tab called "Component Locations" Click on the tab and open the PDF file. Scroll down to page 206 and under "interval wipe control" it shows it is located "behind LH side of instrument cluster" page 202-1 (figure 1 )
This is how you locate the components for your particular model that you selected from the CD.
