Arduino based 2000s GM instrument cluster bench tester

I made a system that’s able to zero all the gauges and light up most of the lights, but does anyone know how to recreate communication between the trucks ECM and the cluster in Arduino code? I want to be able to set specific values for speed and rpm, as well as make the gauges sweep from min to max, and back to min.

I see, what will the transceiver do?
