Umm im not really sure i understand your question but here goes.... it is possible to make the fog work like the factory.... i believe on the factory the fog turns on right when you turn on the car and there is a seperate switch if you wish to turn it off... as for the harness... you dont really need one because the wiring is only a two wire set up not like a complicated one where there are like ten wires going into it.... so if you wanted it to work like factory...ground the black wire to the chasis and then hook up the red to a accesory or ignition wire so right when you turn on the car it is on.... and then put a switch in between the wire so if wish to turn it of it will cut the circuit and the power of the fog.... now if u wire it up this way it is more work because you have to lead wires to the front of the z and then find a place for the switch... but its definetely possible....
