I was probably looking at an 08 wiring diagram. But it said they were wired together so i'm guessing the 5amps is for both front and back?
As I was browsing thru the service manual i saw the bike has a front and rear "Accessory" connection in addition to the plug in the front. But i didn't see much about where to find them or how much amperage they can carry?
These pics should help you find the leads on your bike.http://www.pbase.com/fredharmon/accleads
