Diagnostics plug question

[JMBT]

Just my own two cents here, but I would NOT modify anything just because of Elog connectivity issues. I have used several brands now and they all seem to be junk! Like all electronic crap they do not operate properly all the time.

I hard wired my Qualcomm in, so it does not use the data port at all, and it is grounded separately to a grounding stud all by itself. I still get occasional connection issues. My truck is older too, 2012. The main problem I have is sometimes on start up it pulls the odometer mileage from the instrument cluster, and sometimes it pulls the mileage from the ECM. With nearly 900k on the truck these two mileages are very far apart.

Qualcomm says they work better on newer trucks that only have the j1939 connection. Where as mine is right in the time frame that has 1939 and 1708/1587. But I am sure as shi#t not gonna buy a new truck!!
