Docked Wage

I have a 2004 5.3 LM7 complete takeout with harness and all and would like to know if it's possible to use the older 12200411 PCM (99-2002) to control the newer style DBW throttle body.

I suspect there is some re-pinning that needs to be done and that the TAC module selection needs to be specific.

Can anyone shed light on this?

Thanks, Ken

Wont work with the 2003-up throttle body and TAC. If you want to run that PCM, either go DBC or get the older style TAC and throttle body. Me and my tuner spent a long time trying to do what you're wanting so I could keep the PCM controlled A/C since the 03 up its run on the serial data line. Simply wouldn't work with the newer DBW.

That was my initial thought. Thanks for confirming. You just saved me a bunch of time and headaches.
