does anyone know if a 2003 chevy s10 standard cab 2.2l came with the optional wireing harness for fog lights and if it does where would harness be located,and can you by the fog light kit to hook to the wireing harness and where do I get this kit ,and is there anything special I have to do to make these work

 

This is such a basic circuit, it is easier to wire it yourself than it is to find the harness if it is there. Just make sure you put a fuse in the circuit.
