Rapidbike USB cable pin-out

I'm looking to build my own Rapidbike USB cable - My unit is the Evo exclusive which comes without the cable. I'd buy theirs if it was a better price but can't accept the $AU95 (+shipping) price tag...

I have an unterminated USB-A lead, and an unterminated 4-pin MT090 Sumitomo plug. I was hoping to figure out the correct patching via a multimeter but I'm not getting readings from the Rapidbike USB output connector that make me confident to try (don't want to fry the unit by incorrectly crossing the power and data lines...).

So, has anyone figured out the patching, OR is anyone able to trim back their Rapidbike USB lead to show the interconnect between the MT090 and the USB cable?
