auxillary fan speeds
 

On the 140 S-Class cars, they have two speed electric fans. They come on on low speed by a/c head pressure and on high speed by engine temperature. How would I bypass the low speed and make the fans come on high speed by a/c head pressure instead of the normal low speed? I have heard there is a resistor mounted in front of the radiator that controls the low speed. If a person were to bypass this resistor would that do the trick?

LOCATE THE RESISTOR FOR LOW SPEED FAN AND CONNECT BOTH WIRES ON THE SAME TERMINAL.
