I need to make double-damn sure I got the resistor installed properly. I had to twist the leads together of 3 different resistors to get to the 468 ohms. Those wires are tiny and maybe I didn't get a good connection. (I did connect the resistors in series.)

I'm pretty sure I can pull the codes for the Base module, but I'm still gonna have at the wiring harness leg for the sensor and double check the resistance of the sensor at various temps.

As for version-coding - can't find anything like that on AllData. I installed this controller in an attempt to solve a problem I'm having with the A/C where it wants to dump all the air to the windshield when the set temp on the controller is at or near the external temp. Causes massive condensation to form. The software version that's on this controller was supposed to combat this tendency, but I don't think it made any difference. It never seemed to care performance-wise that it couldn't communicate with the rear controller...

I have the original unit which I had refurbished by Programa - I'll drag it out of the box and reinstall it this evening.
