Mr. Bowtie

We installed an L76/6L80E combo. from a Pont. G8 into a Jeep XJ. My friend was the harness/ECM guru and is no longer involved in the project nor available for help. Engine starts and runs but I don't have anything at the DLC to view live data or pull codes etc. It appears that the pinouts to the ECM are correct. Any ideas where to go from here? Thank you in advance.

Check to make sure the appropriate pins have ground, ign, 12v+ and can bus signals. I assume this is a 2008+ ecm, so it will use the can bus pins.

You should have these pins on your connector..
pin 4
pin 5
pin 6
pin 14
pin 16
