There is a "Spade" on the Ignition Barrel (this is the first one on the right as one looks at the bike back towards the rider,)this gives a power source when the Ignition key is turned to the first position(Ign:Indicators,Horns ect:)I discovered this looking for a power source for the Water Pump, Rad;Fan and Temp Gauge Sender
