The ground pin of a trailer side 7-way connector like the 7-Way Molded Trailer Wire Connector, 4' Long # H20043 you were looking at is the 5 o'clock position as shown in the included picture.

For the vehicle side of the 7-way connector it would be the 7 o'clock position.

I included pictures of both of the wiring positions for both sides of the 7-way connector and a video of the # H20043 for you to take a look at.
