If the wire numbers remain unchanged,
these will not be repeated in the circuit
diagram.
For example, in the sample diagram, wire
1101 is connected to connection point 87 of
relay contact G107, but also to connection
point 2 of component C622.
Wire 2100 (at location number 64) is
connected to connection point 30 of relay
G154, but also to connection point 85 of
relay G000 etc.
