Wire with signal name and direction of signal flow.
In some cases, such as a signal name of 5VDC, the signal is
a steady flow of approximately 5VDC.
In other cases, such as a signal name
HEATER ON (L) 5VDC, the signal is near 5VDC when off and
near 0VDC when on. Or in the case of the signal name
HEATER ON (H) 5VDC, the signal is near 5VDC when on and
near 0VDC when off.
