Connector Views

Male 
Terminal

Cavity/
Terminal 6

The cavities (and wire terminals) in each connector are numbered starting from the upper left, looking
at the male terminals from the terminal side (or looking at the female terminals from the wire side. Both
views are in the same direction so the numbers are the same.) All actual cavities are numbered, even if
they have no wire terminals in them.

Female 
Terminal

The connector cavity number is listed next to each terminal on the circuit schematic.
The cavity/terminal shown below is #6.
