Locate the 3 marked 1x3 female sockets on the main board. These components are designated H2, H3, and H4.

Two photos are shown here from slightly different angles in order to help you identify the locations of these 3 sockets.

Place the jumper board so that its pin headers align with all 3 of the sockets, then push down to seat the jumper board fully into the sockets.

If necessary, push aside the internal black controller port cables so they're not in the way of the jumper board.

The jumper board is not symmetrical and will only mate with all 3 of the sockets in one particular orientation, as shown.

The white printed markings on the jumper board should be facing down and should not be visible after the board has been installed.
