Thanks to a user’s sharing, he has John Deere, NEW HOLLAND etc and makes an OBD2 to 9pin adapter to read with KT200 ECU Programmer.
The method to make an adapter from D-FOX tool to Dimsport cables.
This also works with KT200 etc and Alientech cables.
Also, purchase a JD cable for Dimsport New Genius.
Thanks.
