I just got the theft deterrent schematics last night. It appears that there is class 2 serial communication between the BCM and the PCM. So the only thing holding us back from a "stand alone" setup is one wire to the body control module and it's associated 80 wires that go to various parts of the body. Unless Westers can program the BCM out of the equation, us swappers are going to have to have that to be able to run the engine with the factory PCM. We will also need the keyswitch and key out of whatever vehicle the engine comes out of since it's programmed to the BCM.
