    Question Basic harness/pcm question

    So I have a 2002/2003 escalade harness from a LQ9 (so i have been told). Blue and red connectors, also have the 0411 PCM, and tac module. I am going to use DBW on my swap. Then I have the LM4 5.3 from a 2004 trailblazer-EXT DBW also, it came with a harness with blue and green connectors. What will it take to change the PCM to work with the Blue/green harness? I have not licensed anything yet.

    PCM Service# 12200411 Hardware# 09386530

    Thanks!

    Solved this by getting a 2004 PCM from a friend.
