Step 5: Wiring and installation of USB Socket
Now to do the next step will require some soldering, so make sure to be careful to not burn yourself. In the wiring guide enclosed, you will see an explanation behind the five pins. The yellow wire is almost never needed for any reason other than accessories, and is not necessary to this project so that hole will not be used. The wires have to be inserted in from the bottom, which is the same side as the socket that was removed. A good starting point is to have the Green wire soldered to the center hole. Make sure to use some Flux (i spread mine with a paper match end), and extra fine solder. An easy way to know what wire goes where is the following: (with the triggers pointing up) Red White Green Empty Black. The wires should be soldered in through the top of the board, where the other socket remains. Then run some glue along where the wires feed in to keep the wires from snapping off from the board.
