The connector posted is not the (LED Light bar)connector.
Once your spoiler is removed you will see a grommet on the left side (LHD), if you remove the grommet the connector posted is underneath. Not All Aftermarket spoilers had a large enough cavity to stuff the oem wires inside of them, thus the connector under the grommet is used.
However if you wish to use the LED Light bar connector, you will need this connector
