  • get two pieces of heat shrink shield on each of the wires before doing any soldering

  • Solder the wires to the ends on the casing. Make sure to respect polarity! The negative end is marked with a dashed line

  • Place the heat shrink shield over the soldering and apply heat to seal

  • the bit that protects the wire as it comes out of the casing needs to be cut in half to be reused, and you also want to make the hole in the middle larger so that the new soldered wires fit

  • A bit of hot glue will keep things in place

  • Add some electrical tape for extra firmness and insulation

  • Put back the screw, the sticker and with a multimeter check that you've got the desired voltage output, in the correct polarity!
