It's the green wire at the TPS, trace it back into the harness and that is the color it is at the ECM

I know this is mustang specific info (my 5.0 and ECM are from a 90 GT) but it will help you diagnose.

Angry TPS PIGTAIL & which one does my 89 5.8L take -fixed or adjustable?

The title says it all ....
FYI when i got the TB removed... only thing attached to TB were the mounting screws and some melted plastic...
I literally have no idea which one to buy new or which way the pigtail faces?
Please advise
