I've not removed the fan housing so I can't post pictures of the wiring, but from what I can see.
3 wire motor with purple wire and a silver resistor (that was rivited to the chassis leg), resistor was part of the purple wire.
Control box only had 2 relays in it, the only similarity I can remember is the green foam spacer as seen in Arctics picture. The external of the control box only had the following markings on it.
I've fitted a new 100w 0.5ohm resistor and now have a working low speed & high speed fan
