Two way manual switch?

Is there away to wire in two manual switches that when turned on turn the fans on but when the switches are in the other position, the fan circuits remain stock. The switch is like an over ride to the stock components. Could I use like a double pole switch that switches between the stock circuit and the override circuit. I am also confused on how to wire this. I read all the stuff and I printed out the wiring diagram. If im missing something here just let me know. I am a little confused at how to do this.

If I understood you correctly, you want to maintain the stock fan switch and still run your own switch, yes? If that's the case, you just need to strip a portion of the wire connecting to the fan switch, solder a wire to that, and run it into the car on the drivers side firewall to a switch and then to a ground. Flipping the switch grounds the wire, and the fans turn on, all while the fan switch remains functional.

Yes that is what I want. But what about the other fan?

if you have dual fans, you have a relay for each fan, if you want both to come on at the same time, you need to use a single throw double pole switch and wire up the wires from the relays same as the above post says for one fan, the stdp switch is like 2 on-off switches in one, with on toggle
