You'll have to go back and get the body control module/integrated control module. If you have a factory radio, you might want to grab that also, yours won't work with the other computers. Once you have all that, start replacing them in your car. The key/immobilizer sends a signal to the BCM. If it is right the BCM sends a signal to the PCM. IF that is right, the PCM lets you start and drive the car. Many wires to check before spending money. Known people to do this only to find out they had one broken wire that shut down the system.
or just reprogrammed everything over to that ecu/ecm/pcm
If you have a BCM It can't be reprogrammed(one time deal). I haven't ran across a swap the integrated module yet. The BCM will have 2 or 3 plugs to it, usually under the dash. The integrated module is under the hood. called the fuse panel. This took the place of the BCM.
