I made up a few of these and they are relatively easy to source so I thought I'd put out how it's done and give the info to make your own. I doubt many of you would try this, but here's all the info. The only problem is because of the PCB ordering process you get 10 PCB's at a time. If you can make your own single sided PCB's, I have a board setup that you can use as well.
This is a small PCB with a 15amp relay and 3 fused outputs. It's meant as a central power point for multiple accessories like Heated Grip or heated clothes plugs, accessory lights, USB chargers or cigarette lighter power connectors. Really anything that draws power only when the bike is turned on. You connect one side to Ground, Battery Positive, and Switched Power. You might need to hunt around or check your service manual to find a switched power wire to tap into that turns on with the turn of the key. Once it gets power to the switched power line, the relay clicks over and supplies power to the three outputs though the fuses. The little light goes on when the power is switched on to show that it's working and that it's enabled. The inputs and outputs are wire terminal connectors so you strip a wire put it in the connector and screw it down to lock it in place. The fuses it uses are mini blade fuses.
It's a very scaled down version of this: http://fuzeblocks.com/ but most people only need a few small accessories.
This is the Bill of Materials. These parts are available from Digikey.ca ($8 shipping). You can source cheaper parts for everything except the fuse holders from places like dx or ebay, but I wouldn't. The relay is a proper sealed automotive rated relay. The quality is much higher than the cheap ones with the same footprint that you can get from Chinese discount.
*** I'll post the gerbers later so you can order your own PCB's if you want, but there's a few things I want to improve first.
The PCB's you can get from iteadstudio.com or seeedstudio.com. The reason for the size and shape of these boards is to fall under the 5cm x 5cm size when ordering from these PCB prototyping places. You get 10 boards in this size for ~$10 plus shipping.

Once I put up the gerber files in a zip, all you need to do is attach them to your order and they know what to do.
Anyways, here's the parts. You have the option of using a big through hole resistor and diode or those tiny SMD parts. I use the tiny parts. The big parts are to show you what they look like.
Soldering it together.
The final board.
