How to identify connectors on schematic
diagrams
Each connector is labeled with a connector number and a pin
number indicating to what component it is connected; in other
words, its counterpart.

between associated connectors.

The connections between C.B.A.s are shown below:

with no test pin or components leads, use the foil solder pad to
connect the measuring equipment.

CAUTION: After installation, inspect the connection to
insure that individual wires are not bent or touching other
wires.
