This pin diagram will be useful when viewing these connectors. Sometimes you hold a soldering iron to the back of the connector, and you don’t remember the numbering of the pin. Here is the pin diagram for your reference:

The number of each pins are actually stamped on both sides of any D-type connector. Unfortunately, since they are only moldings, they are very difficult to see as they have no color difference.
