Simple fan switch

Members I have read shoeboxes wonderful diagram about wiring the manual fan switch. I am not interested in using LED lights because the switch wil be located undernear the dash with a few others. I want to see a basic diagram without LED lights and a two speed control. I just want to be able to flip the switch and the fans will come on high speed and still not mess up the computer. Any diagrmas will be helpful and pictures are great.

Just omit the LED's and the resistors, the switch won't need any special setup. Just make sure that the switch you buy is rated at 12 volts DC not AC.

If you can look at it this way, a simple fan switch is one that can apply and remove a ground to the green and blue fan relay control wires. When the ground is applied, it operates the relay(s). On the diagram, just omit the wiring from the middle of the switch to the right (all 12v and LED stuff and also diodes).
