Motorcycle Info Pages Fuel Pump Controller Report: http://www.motorcycleinfo.co.uk/inde...&pageId=233223
Occassionally, on R1200GS motorcycles from 2005-2009, water can leak into the fuel pump controller causing it to fair or the unit can overheat and blow the circuit board, blocking power to the fuel pump, leaving you stranded. This cable bypasses the failed controller and connects the fuel pump to an accessory power socket allowing the bike to start and run.
I recommend connecting the accessory port directly to the battery and that it is fused. The stock accessory port has a 5 amp limit and the fuel pump can trip the canbus virtual fuse with it's greater than 5 amp draw. To install the cable you need to carry a T-20 Torx socket in your tool kit.
