cpotts, I found mine on car-part.com out of a wrecker close to me for $150
super cheap compared to everything else I was finding.
Just a update all with freezing fog and 16 degrees this morning I installed the harness from Deere last night (Everything I was expecting and heard from other members very High quality and labeled very well thanks again Deere) The install took 3.5 hours by myself very simple plug and play. I had no codes installed from the dealer or AE tool and everything works. My seats and wheel were out of a 2015 Ram 1500.
I spoke with Deere regarding the 8.4 missing the "controls" soft key and we have tried the basic stuff ie factory reset checked software version 17.11.07 and all that seems correct. Pre seat install the only thing I had installed from the factory that would have shown up on the screen is the backup camera and I know that to get the seats to show up I will need to have the code added for the seats and wheel. Anyone have any other ideas about the controls soft key simply missing? Regardless, the Heated wheel and seats was well worth the $ the limited wheel wood on top gets way warmer than the full leather
I will try and get some pictures up today of the seats and everything working. Thank you everyone for their help in getting another one done and in the books.
