There is a small wire that comes out from under the pulley. That connects to a magnet that is hidden inside/under the pulley. When you put 12v to the magnet, it sucks the clutch shut magnetically and the clutch plate is then forced into the pulley, getting dragged along with the pulley. If you watch your engine run with the AC off, you'll notice that the center outside of the AC pump pulley is stationary. Push the AC button and the center disc on the outside of the pulley will start to spin at the same rate as the pulley, thereby driving the crankshaft of the compressor, which is a miniature "engine" with pistons and so forth. The AC compressor has an oil pan on the bottom. If you have not done so, you should check the oil level before using an unknown AC compressor. I hit mine without checking it first on the Bay Bridge and the compressor seized due to low or no oil. This seized the pulley too!!!!! I fried the belts and had other motorists passing me and waving their hands in front of their noses complaining to me about the stink of the burning belts. If you do not connect the (light blue?) wire at the AC compressor, it is not possible for the compressor to be turned on. One other thing on belts: Ask for a MATCHED PAIR that were both cut from the same casing. This is important to Chryslers with dual belt systems. Nothing sloppier-looking than one tight belt and one sorta-tight belt due to a few millimeteres difference in diameter. I like to line up the labels so that both are in the same spot as they make their circuit, but that's just me being particular - nobody else would ever notice. Matched belts will have printed labels that line up as they were sliced after being printed.
