Much better having the fan on the temp switch, running the fan all the time isn't good. Above 30 mph the fan usually doesn't run. It pulls a lot of amps, drops the charging volts, and running all the time should be hard on the Junction Box, overheating the fan relay. It might even function as a restriction in 70mph wind.

For me using a toggle switch, I'd try to run it only as needed, and sometime the first day I would forget to turn it on until I smelled antifreeze and the gauge is pegged.

I certainly do appreciate the input, and I would probably forget just that one time and screw up bad.
Thanks!!!

Just to save you some time and head-scratching, here's the procedure for replacing the ignition switch with manual switches.
This procedure removes the "park" state from the bike.

1. Chop off the terminal.
2. Insulate the end of the white/black wire. It is not needed. Alternately, it could be spliced to the white wire.
3. Wire the white wire to terminal 1 of the new on/off switch. This is your power in via the 30amp fuse in the JB.
4. Splice the orange/green, yellow, and Brown/White wires together. Attach them to terminal 2 of the new switch. This powers the turn signals, start button/ignition, instrument cluster, power to headlight fuse, and tail light fuse.
5. Splice the red and blue wires together. This provides 10amp protected power to the tail light. FYI, on a stock bike that 10 amp fuse is the 'headlight' fuse, and the tail light fuse is unused.

You're welcome!

After sleeping on it ... You can still use a toggle like you said, and run the ground to the temp switch. The fan would function normally as long as your toggle is on. So it would be like an airplane, power on, hit all the correct toggle switches, cleared for takeoff.

The temp switch works off of ground, all grounds on this bike are black/yellow stripe.

Thanks Spockster,
Between you and Thorn, y'all saved my ass!!!!
I'm SO GLAD I found the forum, I've been browsing through the threads and I know if I would have known about all of you sooner, I would more than likely have started this a lot sooner and I'm certain already been back in the wind.
