72 Dart Swinger 3.6L Pentastar +T5
I'm still watching this forum topic with great interest and hope.
I showed a younger friend all my V6 Pentastar stuff, still in the wrecked Grand Cherokee, the other day and talked about the problems, your problems in particular.
My friend is of the opinion, though not certain, that for everything to function correctly, each or every electronic smart component in the wiring system must have that vehicle's VIN number code electronically embedded within its firmware. He pointed out a couple of smart components, and sure enough, they even had the VIN labelled on the outside of each.
Am I teaching you something you already know as fact, or is this just juicy thinking?
Keep trying. We're all still watching I'm sure.
