My latest farkle:
The location a 12v plug loose under the side of the seat annoyed me, so...
I purchased a Hella Type/Continental DIN socket from ebay uk
www.towzatronics.co.uk 8.95 GBP ($10.00 aud )
I installed the socket onto the black Battery cover, Right side of bike. The connections are blade type, I added in line fuse and heat shrunk red/black all areas for insullation and
cable tied to other components so no rubbing / chaffing.
The male plug i added onto the original plug charger and now this can double as booster cable for other bikes cars if I ever get a flat battery or need to assist others.
works well and the socket cover fits snugly to avoid dust and moisture.
