PCM and harness compatibility question.

I have a 2002 5.3 out of a Silverado. Well the PCM and harness from a 2011 work? Keep in mind I'll be tuning/programming the pcm.

No, not without modifications...

2011 requires CKP/CMP reluctors to be 58x/4x (there is no converter to go this way).

2011 harness connectors are different, and they're wired different.

2011 ECM/harness has extra functions (VVT).

2011 ECM uses CAN.
