Most will suggest that you wire a 04-08 motor as a Series II w/ out the DBW throttle body. You can purchase a plate to connect the SII TB to the 04 intake. If you do, an 04 w/ auto trans has to use a 03 ECM b/c its the only one that will shift the +04 auto trans. If your running a manual than nevermind. I used Ryan's pinout to make my harness.

The Impala was still running the series 2 in '04. But, it's funny you mention the DBW and TB adapter as I picked up a Gen V M90 local to me for a reasonable price, so now I'm hunting for the parts to complete that setup.

What I haven't been able to find yet, is pinouts for the '04 SS.

In Europe, we don't have as many sources (wreakers, scrapyards etc...) for american cars and parts.
We have to make do with what we find!
Personally, I have a series 2 (year 2000ish) 3800 with a series 1 PCM (year 1995).
Darthfiero did my chip and it works very well. So it is possible to run an ODB2 3800 with an ODB1 PCM.
Yes, you don't have all the inputs (like MAP) but the thing works fine!
