Great idea here! She does run hot after a while in stop and go traffic, even in winter time.
Wiring a switch will be a good place for a couple of posi-taps, to make it easy. (NOTE: Love the Posi's, reusable, neat, as well as easy to take apart if needed.)
I found them here:http://www.webbikeworld.com/sale/posi-locks-for-sale.htm (7 pc assd kit, 9.95 ppd)
or here:http://easternbeaver.com/Main/Elec__Products/Posi-Lock/posi-lock.html (they are about 1$ each piece, 20$ minimum order, us mail from APO Japan)
I suppose a google search may turn up other suppliers too.
Best,
