Make sure that the cable comes off the centre of the circuit board so the housing will fit over it.

Also check that there is about 3mm of stripped cable on top of the circuit board as the strain relief has to fit here (see next photo)

Solder the other braid on the other side, in the opposite corner to the core. Try not to extend beyond the edge of the circuit board

Carefully file off any solder or cable that extends beyond the end of the circuit board.
