Looking for Green Star board (can bus box)?

Hello, it appears at least with all data, there might be limited info on this vehicle so far, but can you provide a vin number so we can identify the correct vehicle setup. I assume since you're looking to do a tune, you want the PCM Can bus network, which is CAN C in the service info currently pulled up. I just picked a random 2024 Dodge Ram V8 6.4L 4WD. This thing has multiple networks and a secure Gateway as well. But on this one CAN C is on the passenger side dash. It has what looks like 2 wire plugs into the Star connector for each module on that specific splice connector, so each module has its own 2 wire connector which they probably put in there to speed up diagnostics, instead of having to de-pin or pull a comb out the splice star connector, which is a good idea. But the correct vin would be best. Ill post the diagrams I'm looking at currently.

The first two diagrams are the OEM CAN C Star connector, (the 1st diagram is just zoomed in so you can see it better), the 3rd diagram is the connector for the PCM (C4) at the star connector, and the 4th diagram is the aftermarket CAN C star connector, not sure why they did it this way,
and correction, this is a 6.4L.
The 5th is the list of networks in this vehicle. The CAN BUS C and the CAN Private Bus System are the high speed networks for more critical systems.
