Okay i have finally had the time to play with the digital HVAC. I got it powered on, Vents work perfectly, and the temperature control servo has been installed and it is operational as well. Also the A/C signal is working so i am good there. Only problem i have left is the fan speed control, it is at full blast all the time. So i need a JDM wiring diagram that has the Digital HVAC in it, all the JDM diagrams i have found have the push button unit only for wiring. I need to figure out what four wires on the harness do and i believe those are the ones that send the signal to the resistor that controls the fan speed. Anyhow thanks fellas..
