Good.
I think the wiring direct to battery option is safest, although a 4amp max load is estimated, I played safe having read one person's issues with wiring loom load. Then it's just the control (on/off and temp) you need to manually set each time you mount or dismount in cold weather.

Oh, Rethals, very bling indeed.
If you want rid of the stock bars, please give me a shout as I want a pair to fit to Sarah Teach's 250Serow.

Timpo.
