Help! W210 Headlamp washer cable wiring

[youngblood]

Does anyone have instructions for installing the wiring harness for the headlamp washer to the fuse box and dashboard switch? I have this diagram but I don't know exactly where everything goes. There is a big red cable attached to the wiring harness that I do not have any idea where it might go. It looks similiar to a positive battery cable. If you have any more diagrams and pictures, they will help also. Thank you in advance for your assistance.
