With the module wire you just tuck it in beside the coil, there is enough space in there for the wire to come through. With that 550 on the bench when I got it I thought the motor was probably toast, had no muffler, no shroud, was covered in rubbish but after finding it had no spark I swapped out the module, put a modified carby on it and with a few pulls it fired up and now runs like a beauty. Another interesting thing I found was the blade carrier on these is only 5mm difference in the hole centers of a standard blade carrier, it is just that they use the blades off a 24 to get the bigger cutting width
