11 Appendix A: Interface Cable Modification Procedure
Some earlier models of John Deere sprayers (4700 and 4710) may use a different style of boom
valve block with a different arrangement of the connectors. As a result, the NORAC 44658-01
interface cable (C12) will need to be modified according to the following instructions (See
Figure 28 and Figure 29 for before and after schematics):
1. Using the supplied GP Weatherpack pin tool, locate and carefully remove the blue/black
wire tee (Main Down) from the A-position of the 4-pin flat connector tee (S4B & T4B).
The blue wire is attached to a black wire that goes across the tee connection (remove both
ends of this tee).
2. Locate and remove the brown wire (Left Down) from the A-position of the 6-pin flat
shroud (S6A).
3. Insert blue/black wire tee from step 1 into the A-position of the 6-pin flat connector tee
(S6A & T6A). Remove the cavity plug from the A-position of the 6-pin tower (T6A).
4. Locate and remove the black wire (Main Up) from the A-position of the 4-pin square
connector tee (S4A & T4A). This black wire is attached to a black tee wire similar to the
wire described in step 1.
5. Locate and remove the green wire (Left Up) from the A-position of the 6-pin flat shroud
(S6B).
6. Insert black wire tee from step 4 into the A-position of the 6-pin flat connector tee (S6B &
T6B). Remove the cavity plug from the A-position of the 6-pin tower (T6B).
7. Remove the black wire that goes across the connection in the A-position of the 4-pin
square tee with the red wire (Right Up) in the C-position (S4C & T4C). Insert the green
wire (Left Up) from step 5 into the A-position of the 4-pin shroud (S4C). Seal the A-
position on the 4-pin tower (T4C) with the cavity plug removed in step 3.
8. Remove the black wire that goes across the connection in the A-position of the 4-pin flat
tee with the white wire (Right Down) in the C-position (S4D & T4D). Insert the brown
wire (Left Down) from step 2 into the A-position of the 4-pin shroud (S4D). Seal the A-
position on the 4-pin tower (T4D) with the cavity plug removed in step 6.
9. The cable modifications are complete. There should be 2 black wires, an incomplete 4-pin
square tee and an incomplete 4-pin flat tee left over.
10. Connect the modified harness to the sprayer as indicated in Figure 30.
