I used the directions when I swapped my 96 engine + engine harness into my 91.
my suggestion is, **** the instructions. splice the wires without soldering. Then go into TunerStudio and calibrate TPS. If you get ~100 for 0% and ~900 for 100% then it's wired correctly. there are 3 wires, giving 6 different combinations total.
You can't break a TPS sensor because it's basically made out of 4 pieces. You can only wire it wrong. e.g. if you're reading 700 for 0% and 800 for 100% then it's wired wrong.
edit: and yes, you need 1.8 pigtail OR you need to use throttle body spacer + 1.6 throttle body.
