The example above indicates a maintenance monitor circuit
continues on sheet number 6 and you must look for find
number 5.

The diagrams use a half circle as the symbol indicating a
maintenance test point for taking various voltage and
resistance readings with a multimeter or the Direct
Support Electrical Systems Test Set (DSTEST). The number
in the top portion of the symbol shows the test point
reference number. For example:
Wire Symbols.
The first number of a wiring harness
identification number indicates which of the main circuits use
the wiring harness. When a wiring harness has 1 as the first
number, it is a turret wiring harness, 2 indicates a hull
wiring harness; and 3 indicates an engine wiring harness. For
example, when you see wire harness 2W159, you know this
harness is part of the hull wiring circuits because the
identification number starts with a 2.
Each wiring harness has its identification number on the left
side of the harness connection points.
The connectors on a
wire harness have the designation P (e.g., P1, P2, etc.), and
the connectors on electrical component assemblies have the
designation J (e.g., J5, J7, etc.).
You can identify the electrical connectors on a wiring harness
or component as either male or female by the way the diagram
shows them (fig. 1-1). Take a look at the schematic diagram
electrical symbols in appendix A, and find the entry for
connector, pin.
You will see that both male and female
symbols are used to represent the pin connector.
