    Default LC9 to L76 swap

    Changing out LC9 and 4l60e from '07 Suburban. Got an L76 and 4l70e as a lift-out with wiring harness, ECM, and TCM. Thought it would be a direct swap and just recalibrate my current ECM/TCM for bigger engine. Found that the '08 L76 harness is a little different (O2 connectors are opposite from my '07 and the donor truck did not have oil level sensor switch). Was going to swap harness and bypass oil level sensor. Then I discovered the '08 L76 has some sort of additional cam phasing so I can't just swap the harness. If I put it all in and run the ECM/TCM that came from the donor truck what problems am I going to run into...relearn VATS? Or should I plug in the original ECM/TCM from my Suburban and program it to run the extra cam phasing stuff in the L76? Would that be a matter of changing the cam phaser parameter to "1" from "0" or would I have to repin wires? Can I power it up with the L76 computer, copy it and reflash it to my LC9 computer? What is easiest?

    All help is appreciated
