9. Connect the 6-pin tower on the valve cable (C03) to 6-pin shroud on C12.
10. C12 has a screw terminal. It must be connected to the frame of the sprayer. Scrape any
paint off the frame where the terminal is mounted. A good location is the bolt holding the
JD wiring harness next to the large connector at the rear of the sprayer frame.
The terminal must be attached directly to the sprayer frame NOT the parallel
linkage. An improper ground can cause UC4.5 Spray Height Control system
malfunctions.
