I'm doing a TDI engine swap on a toyota 4Runner. The 4Runner uses variable resistance switches for cruise control while the TDI is expecting full 12V signals. How can I take the varied resistance signal and make three on/off outputs? I took a digital electronics class in high school but this is a bit beyond my expertise. Diagram of toyota switch is attached. Basically, I want to make three outputs from the G-Y wire. Ideally, they should be 12v outputs to the TDI ecu. I'm probably explaining this terribly so please ask me questions and I can answer them.
