2015 Coronado - No Speedo or cruise control

I did repin 556 and 557 because the very first thing I thought of was loose pins. Resistance was the same at the ECM connector as at the sensor connector. Speed signal is coming from somewhere. My scangauge reads road speed through the 9-pin. In my head I think the problem is between the ECM and cluster. I don’t know how or where to start. I’m assuming that the wires go to multiple places throughout the truck including the cluster. No idea what to look for to confirm the circuits are good.

 

I’ve offered to pay techs for all the wiring schematics for this truck but they say it’s more complicated than I think. I’m not in that world so I wouldn’t know.

 

So now what does the range selector in the transmission have to do with the speedometer?
I changed the shifter boot so I don’t lose any toes to frostbite and when I aired up the truck to make no air was leaking, I was moving the range selector up and down and the speedometer started jumping and fast idle shut off. I was able to duplicate it many times. every time it shut off my fast idle.
Is my issue something as stupid as a loose yoke? It doesn’t move around like it’s loose. And I can’t turn the tone ring.

 

This was totally random when I was making sure everything worked after removing the shifter knob to change the shifter boot. I had the fast idle set to air up. And after the second flick of the range selector the Speedo jumped and the engine went back to low idle. I was able to make it happen multiple times. I don’t know if you have read the rest of this thread. I have not had a speedometer or cruise control for a while. This is the first movement of the speedometer except for when you turn the key on in a year.
