Zumo 220 Co-axial cable - cut!

[Nemo]

There I was, full of confidence and about to make a cable to connect my 220 to the canbus socket by the oil cooler when I go snip and cut the Co-axial cable from the mini-usb to the little box of tricks upstream of the inline fuse. FECK

Now the question is - do I have to fork out £28 for a complete new power cable or is there a mini-usb to 2 wires cable available.

Or any other ideas????

Thanks for helping out this numpty
