LS2 VS LS3 Engine Harness
Will an LS3 harness plug into an LS2 ECU without any issues? I know some of the sensors might be different but I'm in need of a new harness and the one for my car has been discontinued.

Looking at PIN connectors in shop manual, need more info. Year? (2205 has A4) A6 or M6?. Looks like 2007 (LS2) has different harnesses for auto vs. manual and 2008 (LS3) may use the same harness for both.
