Is it an illuminated dimmer switch? Some of them have a little light that lights up the knob. That could explain the extra red wire. If that's not it, I'm not sure what the extra red wire is.
You will cut and splice into only one side of your extension cord (your diagrams shows you doing that, so you already know that part) and you will hook up to ONE of the red wires and the white wire. The green one is ground. You won't use that one for your application. Do you have a VOM (Volt-Ohm Meter) handy? You could just put it on the resistance (Ohm) scale and hook it between the white wire and the red ones (one at a time) and see which one allows more current to pass as you turn the knob towards increased brightness. The resistance will drop as you increase brightness, meaning that the Ohm's reading will move to smaller numbers. If you don't have a meter, you could hook up to light fixture and try each red wire until you find the one that will dim the light. It could be that either one of them will work, depending on the application the rheostat was designed for...it could be designed to control two light at once. Did it say Single pole- Single throw? It could be one of the fancy ones where if you click it once, you're controlling a light, and if you click it the second time, you are controlling a fan or something else....made for situations where you have a ceiling fan with a light fixture built in and only one switch box on the wall.
:I bought myself two dimmer switches today. Both say single pole, and i have extension cords with the female end cut off. Now, the dimmers have 4 wires on the back part. two on top ( one is red, one is green). Two on bottom (one is red, one is black). Every diagram on the net ive seen shows you hooking up only TWO wires from the back of the dimmer to the one strand of the extension cord. WHICH two wires am i supposed to hook up? Some more info on the dimmer, its a push on/off type with a dial to turn. Completely counterclockwise is off. I bought them from ace hardware. Someone PLEASE help. Ill be monitoring responses so if you have questions please post and ill answer ASAP.
