Use of Pin Boards.
Pin boards are used to shape the wires for binding into a harness.  Figure 6-2 shows a typical pin board diagram.  The pin
board  diagrams  of  wiring  harnesses  for  fire  control  equipment  appear  in  the  pertinent  technical  manual.    Reference  is
made to these diagrams as applicable in the rebuild instructions.  Individual wire routing for the boards will be found on the
applicable wiring harness diagram.  Cut and stamp marker sleeves to suit from bulk sleeve material.

Coding Wires.
Fit  marker  sleeves  on  the  conductors  in  such  a  manner  that  the  identifying  characters  can  easily  be  read  from  one
direction when the wiring has been installed in the equipment.  In the case of two rows of connections, on opposite sides of
the terminal block, it may be more practical to arrange the sleeves so they may be read from opposite directions. However,
all the sleeves in each individual row should read from a single direction.  The position of the sleeve designation will be
shown in the wiring harness diagram referenced in the applicable rebuild instructions
