Erik, I have a local pick-n-pull that has great prices. I cut the engine harness about a foot past the PCM, and the only charged me for the PCM (I didn't want the PCM, I wanted the connectors).
So I just did a little more research. The car I found was a 2005+ Saturn Ion w/a 2.2 L61. These are ALL OVER the junkyards in my area. I walked past probably half a dozen of these cars. But that's not the good news, the good news is two fold:
1) The 2005+ Ions with the 2.0 have the same connectors as the 2006 4.2 - all three!
2) So do the cobalts!
Edit: This harness is way too expensive but you can see the 2 P12 style connectors.

So....who knows how to tell the difference between a 2.0 and 2.2 on sight?
