on mine it showed
VSS
Water temp
Trans temp
gear indicator
Tach should show up but i ran the white wire from the ecm to the bim
check engine light i also ran the tan mil light from ecm to the bim
i didnt have cruise so i dont know if the light shows up.
oil pressure is not shown. i had to run the DD sender unit and wiring.
also wiring in a 2nd aldl connector doesnt work. when the DD is plugged into
1 port it wont allow a scan tool (gm tech 2) or a tune tool (hp tuner or efi live) to communicate with the ecm. you HAVE to unplug the DD before trying to communicate with the ecm anyway.
this is just my experience on a 411 warren pcm which i have done a few swaps with.
