Note which way up the port you removed was to find pin 1 then it's basically the same as this except instead of soldering to pins on a connector you solder to the pads, the last image in step 2 is the key one.

If you doubt your soldering start with the two pins in the middle and get them perfect - the edge ones can be positioned slightly wider than the pads so are easier (and here you actually want to bridge two pads on one end making it easier still)

A smaller soldering iron tip will help
