Hello,

I'm trying to gather information about all the 12200411 PCM pins and functions available.

Here is a spreadsheet I created looking at wiring diagrams for some 2000-2002 LSx based cars and trucks. Does anyone have information to fill in the remaining blanks?

I'd especially like to know if there is an oil temperature sensor input available for logging, I know there's a PID to get oil temp value (GM PID 1602).

Don't have it in front of me, but I have alldata. I can pretty much pinout any pcm. Best I can remember there is not an oil temp circuit..... Will check tomorrow and get back with you.

Seems like it matters the application. The first two are for 01 express van 5.7 the second two are for 02 k1500 5.3.

Hi dzidaV8 again! haha,
I actually spent a lot of time comparing differences in wiring of the 0411 PCM for different cars/trucks. I'd like to add to this worksheet you have (for example, Pin 58 in the Red Connector 2 is for the Engine Oil Pressure Sensor Signal for only the Corvettes). I couldn't find anything about oil temperature in my collection of resources yet.
So a suggestion: could you change the header row titles for columns D and E from "Function", "Alternative Function" to the platform names instead? Like columns titled: "F-body", "Y-body", "GMT-800 Trucks", "GMT-600 Vans", (and there's more like the S10 and Trailblazers too)?
Trucks/Fbody/Ybody have some pins that were re-purposed differently (for example the HVAC controls).
And adding the GMT-600 column might be very helpful for the 24x LT1 crowd (people like me, haha).
Or if it's alright with you, I'll make these title edits and populate the workbook with what I've found.

Your thoughts?

The Aussie VY Commodore (later model Commodores were released in the states as the Pontiac G8) '0411 pinouts are here: viewtopic.php?f=32&t=134#p21742

I havnt compared them to this list though, but could be considered as another implementation.

The G8 was the VE Commodore.
The LS1 was the Pontiac GTO (Aussie Monaro) in its first year before it got the LS2 in its second year.
