OK - I too was thinking the SUUNTO lead would be a good extra addition, so ordered one off Fleabay.
I used a standard voltmeter to check the connections on the TS cradle (pics will come).
With the clam shell opened to the left, so the 4 contact pins are on the right, the voltages (top to bottom) are: GND, +2.00V, +2.57V, +5V. [This is plugged into a wall plug charger, not PC)
Using the meter on the SUUNTO lead, oriented to reflect the same top to bottom pinout (for me the lead comes out of the right of the plug, and SUUNTO is upside down),
then THE GND AND +5V ARE REVERSED, SO THIS WOULD PROBABLY SHORT THE TS BATTERY/DAMAGE THE WATCH.
Im in the process of hacking the cable, just by cutting open and switching the cables, but initial feedback doesn't show the that the TS is charging.
[I have only swapped GND and 5V, so wonder if the other lower voltages are needed]
I do also see that the SUUNTO clamp pins and TS pads don't line up exactly, and the clamp doesn't hold on very well to the watch....
More updates later.
