Auxiliary Fuse Box

The ST1100 fuse box is located under the left side cover next to the battery. Honda has provided one 5A Accessory power supply, which, let’s face it, is a bit limiting. If you’re going to be installing electrical accessories, a good starting point is to install an auxiliary fuse box.

I installed a new switched fuse box via a relay. (This fuse box only gets power when the ignition is on, which saves your battery from draining when you’re not using the bike).

I ran a wire from the 5A accessory terminal to the relay, and connected a heavy gauge cable from the battery positive terminal to the relay. The relay feeds the surface-mount 8-way covered fuse box:

which I located on a piece of plywood in the tail housing (I later moved it into the Givi top box).

The plywood also provides a solid base for the Autocom unit. Here's a photo:

A heavy gauge cable also runs from the battery negative terminal to a common connector (coloured green in the photo).

The white plastic "pillar" you can see just to the left of the Autocom is a removable plastic cover, which insulates a copper post which is connected to the live feed from the battery. The problem with a Pan European is that if you ever have a flat battery, in order to connect jumper leads, you first need to remove the seat, then the left pannier, then the entire left side panel in order to access the battery. The copper post shown here enables the easy connection of jumper leads, and only the seat needs to be removed.
