68448026AA is the part number I used and it fixed my truck's communication issues so I would think that it's most likely not your issue. I know by talking to you and reading your posts how thorough you are so I would be surprised if it's an issue with your harness but it wouldn't hurt to check. The problem my truck was having was a communication issue but was acting a little different than your's is. I lost control of the directional blend doors to control airflow which was caused by the drivers temp blend door actuator being incorrect even though the drivers temp blend door was operating normally which kind of shows these things can act strange. I wish I had more info but since only three of us have done the Dual Zone Conversion we don't have much info to go on yet. I would say the next step would definitely be to check the harness. Since my truck and STecoD's truck are functioning normally we know the actual upgrade works.
