I need help with how to wire up a manual switch for a cooling fan.
Has anyone done this, and if so where did you put the switch, what kind did you use, and can you provide a wire diagram? Verbal or small sketch?
Any help at all would be greatly appreciated.

I have never done this but I would mount the switch on the left side of the fairing so you can leave your hand on the gas/brake. Wiring could not be easier. Get a SPST switch (which only has two leads). Find the radiator switch, it's the only electrical device attached directly to the radiator (not the fan). The radiator switch will only have two wires. Wire the SPST switch leads to the radiator switch in parallel, one wire per lead, leaving the radiator switch still attached to the wires. E18 connectors make this process quite simple. It does not matter whcih switch wire goes where as long as they are not shorted together. One caveat, the power to the radiaotor switch may be constant so it could be possible for someone to turn the fan on while the bike is parked and drain your battery.

ok, here are some pics. here is where i mounted the switch, right below the kill switch. i had to open up the unit, cut a little hole, check the fit, cut a little b*****, check the fit, shave some more, check the fit a little more shaving, and then finish.



and this is where the wires go too. its a simple switch, with two wires, the switch closes the loop between the two wires. the wires coming out of the radiators temp sensor is what you need to splice into.



let me know if i can help you anymore.

So how would this be done to have the switch still come on automatically as speced, as well as having a switch to manually overide the switch for supplemental cooling?

Because you're wiring the manual switch in parallel, the fan would come on if either the manual switch is closed or if the radiator calls for the fan.

Ray got it. on my bike though, the fans aren't set to come on till about 225-230 degrees F, so by the time it reached that i would be hurting. this way i can switch the fans on if i'm stopped at a lite or something for too long. it doesn't stop the temp from going up to 220ish+, but it makes it go a lot slower when climbing up to those temps.
