	Once you have identified the lines on the schematic, you need to identify the pinouts on the transistor and match them to the schematic. Refer to the diagram that comes with the transistor . Lots of transistors use standard package types. Some transistors have unusual pinouts so always checkthe diagram or obtain a datasheet on the transistor.
