You do understand what I meant. If the GEM has to have one of the three known signals, then a new one has to have one of those(the AWD resistance) to work. The switch would have to be altered to work with a specific relay, which has a resistance, and a resistor in the switch to provide the A4WD signal. Not that big of a deal, if the signal will trigger a relay, we could find the resistor to make that happen.
I agree that first the voltages need to be known, which are the input and return wires. Then a working truck like Mickey's or yours needs to pull the switch plug to see what that does. I may be done in a couple of weeks, or who knows depending on weather and work. I'm sure that disconnecting the switch will do no harm. The test will need to be whether everything works with the 4406, including what the brown wire has for power during operation. I expect that the dash light and nonfunctional 4WD will scrap that idea. We will be looking at the switch modifications and external relay as we just discussed.
