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? :)

Do I hear a STICKY coming? This is awesome. Thanks allot. I have been going over schematics for 04+. This is great. Thanks again!!!
 
Re: 2005 PCM Pinout?

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


Re: 2005 PCM Pinout?

hey jon, post all the years in here (if they are different from one another, otherwise just say a range that they apply to) and ill move this to the how-to section.

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.
 
Re: 2005 PCM Pinout?

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


Re: 2005 PCM Pinout?

thats cool. thanks for the info.

ill move this into the how-to section and rename it.
 
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... :th_sick2:
 


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
simon
