I have a 2006 Trailblazer SS with a LS2 (rod knock)... I am selling the long block but I need to know if the engine harness from the TBSS willl work with a crate engine 5.3 I just bought. I plan on using the DBW and all accessories except the A/C on my CJ7.

Also the doner 4l70e... where is the tcm? Is it sep from the ECM?

How can I identify the ECM that was in the TBSS?

Thanks.

No one? Bueler?

The TBSS ECM was an E40 (24X LS2). Major difference will be the the E40 does not use a TAC Module while the 411 style PCM (older LS1/Vortec 24X) does use a TAC to operate the drive by wire. Other items such as the knock sensors and injector connectors will be different. Also, your cam sensor is in the back on the 5.3, instead of in the timing cover for the LS2. Note, I am making the assumption that you are using a 24x 5.3 engine.
