Align the connector, ensuring the center pin can reach the the spot on the board where it needs to be re-connected.

Solder the barrel of the connector to the metal bracket first, try not to let it get too hot. You may want to use a solder gun with dual heat of at least 50 watts for this part.

When that's done don't forget to solder the center pin to the board using as little solder as possible, to ensure there's no grounding to the metal cover.
