I had read reviews about the harnesses before i bought one, that talked about people having some wires swapped, but they said their tech support helped them resolve it quickly. I went ahead and ordered anyway and didn't have any problems. If I remember, this is your 2nd harness from them too...

Another great resource is the LT1swap.com site ... this page - https://lt1swap.com/2000harness.htm

I think I recall you are DBW, here's the page with all the PCM pinouts there - https://lt1swap.com/2004vortec_pcm.htm

If you are DBC it's here - https://lt1swap.com/99-02_vortec_pcm.htm

Good Luck!
