Using same diagram for mine with 02 R/T harness.

Works fine.

Without tach adapter tuning is limited on safcII to throttle position, no clue about neo.

I'll go out on a limb and say tach adapter helps fine tuning since you can also tune by rpm and not just throttle position........but it will work since the tuning is roughly 60-70% TP biased and 30-40% rpm........As you have already read.

I'd suggest an accurate wideband and a "new" 02 not someones used wideband 02. There is enough tuning available with one to kill an engine rather quickly.

Sidenote avoid 5 in 5 out setting. Use 4 in 4 out or 6 in 6 out.
If the parts car is cleaner rust wise than your car, swap the inner dash panels (VIN) and use the parts car with your title.
