GM LT4 Engine to Swap into Nissan 350Z

Hi,
Thinking of buying a half cut vehicle with the LT4 engine, manual transmission;
Will swap the engine and the factory ecu/wiring loom into a Nissan 350Z,
My question is : what other control units or electronic bits and pieces like the bcm, ...etc I need to start and run the engine successfully in the Nissan ?

Thank You
