Integrating the body controller can be tough in the newer cars, but can be overcome..... just be glad it is not a newer GM car with body module, security module, and PCM all communicating over a coded serial connection! Thoses are tough!
I should hope that the shop you have working on your car has the factory Lexus/Toyota EWD (electrical wiring diagram) book and factory service manuals for both the car and the donor car.... That will clear up a lot of head scratching and dangerous guessing.... I am a very experienced engine swapper, and that is he first thing I buy to start the swap. All the swaps I have ever done have started on the first turn of the key, and worked as they should.
