This is the plug that I used for that socket, but as far as I know it's only meant for light loads such as a satnav, which is what I use mine for. No doubt someone else will be able to clarify that point.
Plug and Play! R NINE T (2015 on) R1250RT R1200ST R1200S R1200R S1000R WIRING Wires are numbered and need connecting as follows: No 1 lead earth ( Black lead ) No 2 Not in use No 3 to red lead on sat nav ( Red Lead 12v ).
Looks like it could be used as an ignition switched trigger for a relay if you fancy a bit if DIY wiring.
If not then a Healtech Thunder Box might be the easiest way and much cheaper than an EZCan.
The Thunder Box simplifies and safeguards the process of connecting aftermarket electronic accessories to your motorcycle, such as heated grips, GPS, etc...
