oh and about the radiator fan switch, its impossible to hurt anything if you do it right... your thermostat switch will have two wires coming off of it, all you do is tap into those wires w/ the two wires coming off the radio shack's rocker switch, its impossible to do it wrong, the only thing you could do is have the wires backwards which would simply make the on/off position of the rocker switch itself backwards, but that doesn't matter... also if you tap into the wires, not splice them, then the fan will stil work on its own at the pre-set temperature... i mounted my switch on my right handle bar and covered the wires in black hose from lowe's, blends in w/ the two throttle cables coming off of the same handle bar perfectly

this is the switch i used


and i used these posi-tap connectors to tap into the thermostat's wires, they have a needle in them that just screws into the wire, no splicing necessary
