Just make sure it's insured fully before you push it over...
What RIP was saying is correct about the PCM. The dealer told me the PCM and BCM communicate with each other. After you replace the BCM they have to DRB it, program it - the PCM that is - to accept the BCM. After this the PCM and BCM will communicate properly. Even if you replace the BCM with the right one and it's not programmed through the PCM you will still have problems. Hope this helps.
Just to edited, this info is for 4th generations, I just noticed yours is 3rd, sorry about that, this may be true on 3rd generations but not positive.
