Listers,
Question about DB/D-Sub connectors eg: DB9, DB25, DB37, etc.

Garmin recommends, and it seems to be common practice, that all holes in a given DB connector have a pin/socket installed, even when there is no wire connected to that pin.
Why is that?

Where does Garmin recommend that? I don’t recall seeing that in the G3X installation manual. I’ve been an EE for nearly 40 years and don’t recall this being a common practice. Most weather resistant connectors have plugs available specifically for the holes in the connectors that aren’t loaded.
