Order the color of wires that are already installed in your K-9 Dryer. 

NEW variable speed switch and circuit board installed on every new dryer. The upgraded component delivers noticeably better performance:

• The motor activates with further rotation of the knob for more intentional control.
• Even though the motor starts later there is greater sensitivity and a wider range of speed options, giving you finer adjustments from gentle to full power.
• Results in higher quality grooming with better precision, reduced noise potential when dialed low, and more consistent drying for every coat type.
