Check Engine Light

.

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.

No oil pressure?? That's not cool. What about a 2005 PCM? Will that show oil pressure? The PCM/harness has a oil sender so I feel like this should be displayed through OBDII/BIM.

anyone have issues with their gauges cutting out? I have the BIM with VHX in my pickup. High RPM accel 'power' them down and they restart. Its only the gauges run through the BIM module that have seem to have this issue. Using the 0411 PCM as well. Just kinda frustrating cause i cannot see the rpm or speed when flooring it.

Did you figure this out?

EDIT: Nevermind - seems you got oil pressure, which is pretty awesome.

I saw your original reply that I would have to add the wiring to the dash. I think because I rebuilt my own OEM harness, following LT1SWAP.com instructions, and used his wire maps on his website, I made sure I pinned that out and added the wire(if it wasn't already there). And maybe the 2003 6.0L PCM has the Oil sender provisions. However, this was a year ago so I may be a little hazy on the exact reference here, but doing my research, all these computers were usually the same blueprint with different tunes so I think with a change to PCM tune you can turn the oil sender feature on/off in all these models. Then if the harness didn't have the wire, you just add it.

Yeah, I was mistaken. 99-02 trucks I dont believe have provisions for oil pressure in the PCM but it can be added and enabled in the red/blue PCM's, but 03+ with the green/blue PCM's do. I am using an 06 PCM with a PSI harness in my swap, but I believe my engine has a pressure switch rather than sensor. I'm using a tablet + OBD2 reader for a dash, but the PID for Oil Pressure (22115c) with what I believe to be the right equation is only showing "0" or "1."

Your comment actually made me dig further into adding oil pressure to my tablet display, so thank you for following up!
