Yes you can..... but:
1. Wire it so that ignition switch will turn off fan feed.
2. You won't have a fan cool down after motor is off.
3. Why do you need to do this?
4.Do you want to have the sensor still work and your new switch?
You can connect the two wires at the sensor together. No extra switch necessary. But it will be on all the time ignition is on.
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
