I have the china cat com 3. Says it's setup for j1939 but my trucks are 6 pin will the oem cat 9 pin to 6 pin help me connect!!? Looking at the pinouts for the cat cable it looks like it'll give me what I need as far as having j1939 power for my cat com
Cat Comm Adapter 3 should read both networks. Been a few years since I've played with one though. Maybe a setting in the program to switch between the 2 network types?
