PCM Pinouts

I'm looking to bench-flash my 05 computer for a potential buyer, and my car is long gone. Anyone have the pinout for the 04-08 Grand Prix?

Enjoy

Do I hear a STICKY coming? This is awesome. Thanks allot. I have been going over schematics for 04+. This is great. Thanks again!!!

Thank you for posting this! Huge help.

Your welcome, Alldata does come in handy sometimes

I'm jealous! Any way you can get the pinout for a '97 and a '99, as well?

From what I know about W-bodies, the 1997 PCM is one of a kind, 1998-2003 are all the same, 2004-2006, 2007 is different again. Monte Carlo and Imp 2000-2002 and 2003-2005.

So this mean I have to post the 2007 Grand Prix still, I believe the 2004-2006 GP is the same as a 2003-2005 Chev. Also 1998-2003 GP is the same as 2000-2002 Chev.

Ok give me a few minutes to get the 2007 images.... if it is even worth doing since they are not tunable anyways.

2007 has about 20 connector diagrams, depending on some NU6 option or not. If anyone really wants them all I will post em up.

thats cool. thanks for the info.

ill move this into the how-to section and rename it.

sticky sticky. good info

nothing is stickied in the how-to section. ever.

Maybe move to the General Tech and STICKY there? This is really good info to hang onto. That's why I Copied all the files.

What pins needs to be connected to bench flash an 04+ computer. I'm in the same boat but i'm not sure which pins to connect here...

Thanks for 2004 pinout..

too bad.. i dont see performance switch option :-/
ill have to keep hunting

Would I need to use stock tach or can I use aftermarket? Also, wanting to run electronic cooling fans on the radiator... L67 going into sandcar!

is there a way to get the pin out on a 1998 gtp?

maybe the fuse box with that if not a hassel?

thanks in advance

hell you can get all these? Can you get the pin out for the abs module on the 05 gxp je4 package?
