I got the harness re-pinned this morning, you were right took ~30 minutes.
Most of which was labeling the wires, and double/triple checking proper locations when swapping them.
No tuning yet, need to see if the PCM actually works before I bother with that.
Maybe tomorrow I'll have time to plug it in, and see if I can communicate with the PCM.
If everything checks out, I'll try to start it just to see if it'll run.
