5.3 DBW to DBC conversion Which PCM etc.

[SoCal Cruzer]

I have a 2004 5.3 and I'm running a 200-4R trans. I don't have any electronics so I need a harness and PCM. The motor came with a DBW throttle body and want to use a DBC that I have and need to know which PCM and harness I should be looking for. I got a line on a 2003 LQ9 PCM and harness thats DBW, but will this work with the DBC throttle body and if so are there some other wiring to do for the IAC and TPS. I think I'm suffering from INFO overload. I thought I had this figured out. I want to run DBW in order to control the TV cable on the 200-4R and lack of parts.

If it were me I would use a 1999-2002 F-Body M6 setup or a 2004 GTO M6 setup.

I want to say the PCMs are the same for all of the F-bodies, GTO, Corvette and Light Truck from 99-2004, so the PCM you have should be able to take a stock program from whatever harness you go with or find from this first suggestion. If your PCM has a blue and red connector, you should be good. If it has a blue and green connector, I would say it will not work.

I would also contact John at Speartech to see if he can modify your current harness to go to DBC setup. I do not see why it could not be done without too much trouble.

Hope this helps.
