2012 Dodge ram instrument cluster Arduino interface

[RedneckTech]

Hi,

I'm working on a project where I'm taking a 2012 Dodge ram truck instrument cluster and installing it in a 1996 Dodge truck. I plan on making an ecm with an Arduino or esp32 to read the sensors and broadcast to the cluster on the can bus. I have the cluster wired on the bench and powered up. Problem I'm having is the "on" message. So far I dump some messages from my working truck and replayed them to the cluster, but still getting "no bus". Maybe I missed the message I'm looking for. Any help is greatly appreciated.
