What harness for DBW Red/Blue setup?
5.3 24x block with 2006 GTO Intake Manifold/Fuel Rail/Injectors/GTO DBW Throttle Body.
I have a 12200411 PCM (Red/Green) that I plan to send out for VATS removal and a base tune.
I found someone selling a Blue Green harness out of a 2005 truck, does it make sense to start with that? I’m thinking it has the DBW TB connector on the engine side already and I would just need to repin for the PCM connector differences and file down to fit?
If my understanding is right the question is whats worse changing the PCM connector or changing a DBC harness for a DBW setup?
I am also concerned about TAC module compatibility. LS1Tech recommends keeping the TACS and PCM same generation but will a Red/Blue compatible TAC work ok with my GTO TB?
Advice appreciated trying not to make any costly mistakes
U can take a dbw harness and ecu and make it work as dbc. I have a few spares laying around and i could tune one if u needed.
If interested pm me.
