PRND321 Cluster Display

Just plaging with the cluster PRND321 display. There is no physical connection to the transmission or shift mechanism. The transmission range positjon switch is connected to the PCM and the PCM sends serial data messages to the cluster for display.
ps: you can hear what I believe is the backup lights relay on the BCM ( bare circuit board) click as the display goes into or out of reverse.
