HI IAWEBSTER,
i have ordered a power socket off E-bay. When it comes i plan to wire it into the inside of the grey plastic inner cover for the indicator, taking the live from a power lead i have already put behind the plastic cover underneath the headlingts.This will power a female 12V socket and then the normal car power lead should plug into that, my only concern is that there is enough room in the GIVI bag for all the spare lead..... This is ignition activated so should protect the battery. I really need to get this sorted as i went for a 350 mile ride around Wales yesterday and had to keep stopping to check the road map.......
