Jeff,
I followed your tutorial and my voltages are way off even after adjustment. I got 2.45, 2.6, and a pot that cant go past 1.9. The electronics store I have on island (Okinawa, JP) doesn't have the pots so I'm kinda stuck. Here's where my real question comes in....I didn't get the 4WD light on until I was removing tint from my back window (also turning my car off and on occasionally for some background music). Is it possible that I just smashed on a wire somewhere around the back seats and broke it that way? I am getting error code 13 which to me sounds like it has a connection to the sensor but still it hangs in the back of my mind about looking in the wrong place. I'm interested in buying a completely electronic system like the one you're making and there is another one built and currently being tested over Here
