10. Remove the wire tie from the left and right LED cluster harnesses and disconnect the right LED
cluster harness from the Main PCB at connector location J9.
11. Connect the new LED cluster harness to the left LED cluster assembly and run it through the z-mo-
tor mounting bracket and use a twist-lock cable tie to tie it with the adjacent harnesses to the
z-motor mounting bracket (Figure 2).
12. Run the LED cluster harness following the adjacent harnesses down to and through the left lower
arm access hole (Figure 3).
13. Run the LED cluster harness through the left lower arm access hole to around the left inside pe-
rimeter of the base and connect it to the Main PCB at connector location J9.
