im reading post that rocket5979 wrote back from 4-28-2012 about making a retard function in the ECM for a 2009 G8 GT using IATS and a resistor. He listed the parts needed for the construction of the unit to wire into the factory wiring. He list 2 resistors but in the diagram only shows using the 100k ohm and not the 5k ohm...where do i use the 5k ohm resister?
