What I got accomplished today...
Removed old wiper fluid box and installed stillen supplied new one. It's pretty cheesy: first it's not made to fit the wheel well mold so the anchor points aren't flush. Second, where they want you mount it, it is impossible to installe the back screw so I had to drill a hole and zip tie the whole thing to the frame to keep it securely fastened. Third, it doesn't have a place for the float sensor so they make you flip it upside down and zip tie that in so it fakes the system out and thinks the washer fluid is full. Lastly, and my biggest bitch here is that it doesn't seal well to the OEM neck so if you overfill the tank, it's gonna leak.
