S2R1000 fuel pump wiring

After some time spent checking out my S2R1000 which cut out whilst riding, I have discovered that the red wire which leads to the fuel pump has a break between the plug outside of the tank & the fuel pump itself, the fault seems to be within the epoxy resin plug within the pump mount flange, any one else had this problem, or any ideas how to fix, Ducati want £650 for a new pump assembly. Ca Cycleworks have a wiring harness replacement but can't see anywhere over here I can get one from.
