Ok, just got the kit in. Looks like they upgraded it to USB!
Did yall hook up the power & ground at the diagnostic plug?
Also the pigtail has 2 sets of data wires, one set is for J1708/J1587, and the other is for J1939 or RV-C data links.
According to VMSpc my Allison tranny may be able to readout fluid temp. Is that what the other set of data wires is for? How do I know which is which? I'm confused
