Right Joy Con rail connector pin connection

If bought a faulty Joy Con where both connectors to the rail of the joy con where missing, when i soldered the right connector back on the board I noticed that one of the pads is ripped of the board and I can not find out where it should connect to so I can run a wire.

I connected the joy con to the switch with the missing pad and it is detected by the switch, can be charged and is overall working but regardless if it is docked or not the switch will show it as wireless connected.
