ECM 3 ports or 2 ports?
So! A riddle:
A 2.4lt ECM has 3 ports, and a 2.2lt has ECM has 2 ports. What's the extra small blue port for and do I need it? Could I use this 2.2lt ECM on my 2007 HHR 2.4lt engine?
Thanks!

I don't know exactly what the connector is for, but there is obviously another harness that plugs in.
I wouldn't think that a different part number could work.

The ECM for the 2007 2.4L seems to be unique to that year.
2008 they both use the same part 2 connectors.ACDELCO 216140 {#12597125, 12612397}
2009 both use the same ECM, the one with 2 connectors. 2009 has VVT.
They are completely different for both in 2006.
There are several updated part numbers.
