New Speed Triple 1200, Spare Power Offtakes

Hi got the new RR version, loving it. I want to connect Tom Tom to a power off-take so that its “off” when ignition off. Thinking of using the connector for heated grips as I don’t have them or running cable to under seat of bike where there is 3 auxilary fuses but no clear indication of how to access connectors to any of them. Any suggestions please ?

 

Thanks, not spotted that, will have another look.
