I was asked to post some pics of the Autocom install on my K13.
The Autocom box is installed under the LHS tail section.
The pillion cable exits by the rear grab handle and the rider cable exits below the left tank panel.
The image in my earlier post shows the Autocom mounted in a tank bag; an arrangement I found convenient when using multiple bikes. The tank bag was lined entirely in a Velcro type material so I could just 'stick' the autocom and radio in place.
When mounted the bag looked like this and was powered from the accessory socket.
hope that helps,
Martin
