The LS2 is Gen IV and very different form the Gen III LS1. Just source a Gen III harness and PCM be easier and cheaper.

If you bought the Gen IV harness just sell it and the ECM. And buy a Gen III or a ready to go aftermarket one and pick up a used Gen III PCM save your money.

It could be made to work. You have add the front mount cam sensor and cover as well add the Gen IV side knock sensors. Use an early Gen IV E40 ecm with a 24x tune. I doubt the later ECM will work. Plus it will work with DBC either so you would need a DBW TB and pedal as well. So that's more money. It will add up. Just those parts alone will be expensive vs buy a Gen III harness and PCM that plugs right in.
