I just bought a 2004 650H dozer and the radio is missing... most likely it was stollen sometime in the past. The JD dealership wants almost $600 for a replacement, but I can get a much more modern radio with tons more features for less than $70. A wiring diagram for the original JD radio wiring harness would really help assist with this, but have so far not found one on the Internet anywhere. I have been told that many JD machines used the same radio.

Does anyone out there have a wiring diagram for anything even close to this machine?
