My bike came with a 12v socket mounted on the handlebars>>>>
My mounting had a screw missing, and kept on moving, plus the handlebar was too narrow, so it had gaffa tape wrapped around to thicken and take the mounting. I never was happy with it. So..... i went about mounting the socket as i'd seen in a photo. Its mounted on the plastic panel just inside the indicator.
Heres how i did it for anyone thats not seen it before (like me till 2 days ago)!!
Take off the plastic panel with the indicator on. (i took off the left hand side as sitting on the bike) Just 2 allen key bolts, then unclip the indicator wire connector.
When you have this off, undo the single indicator allen bolt...which also undoes the inner and outter pieces. >>>>>>>
Then, use the socket locking plastic screw on thingy as a template, and score on the inside of this where you want the socket to be mounted, and cut out the hole>>>>>
There already is a hole for the indicator wires to come out of the panel, so use the same hole for the Socket wire>>>
Put the two pieces back together and then put back on the bike! Simples!
Heres a few pics of how it looks now>>>>

Whilst i was at it. I decided to fit a second power socket under the seat. Ive had issues with when it rains, as the sockets are only waterproof when the rubber cap is on and not in use. So thought id fit another one that can run straight to my tank bag and can be left connected when its lashing it down.
I took out the tool pouch and used this space for the socket. Tool pouch is now in my pannier.>>>
and because i usually have my satnav and phone, and the wifes phone on charge whilst reaching the next campsite, i use a triple socket>>>
There ya go. Hope it helps someone!!
I would be just a little worried if the battery can take all the aux. plug inns usage of power .. but yes great idea on the 3 pluger ..Nice Sykesy
