    6.0 Swap PCM question. Have 12570558, do I NEED an 0411 pcm? 97 RCSB

    So i am swapping a 6.0 into my 97 RCSB, the pcm that came with it is hdw no 12570558. I cant find much info regarding the swap vs all of the info I'm finding for the 0411 pcm. Will this one still work without making it a standalone harness?

    Will 0411 support DBW?

    That hardware number is for a 2003 PCM. It will support a DBC or DBW throttle body. The 12200411 will support DBW but the components are harder to find. Your 2003 PCM will integrate into your 97 harness the same as the 0411 will.

    Thanks Lextech. Thats what i thought. The guys on the LS swapped OBS facebook page made it sound like I was going to have to get a 0411 PCM. Good to know!

    How did your swap come out? I'm in the beginning stages of planning mine. I only have the 6.o with no wiring just engine.
