Can't you just unplug it and plug the factory haresses back together.

Kinda curious what that was for, considering its hooked into the TPS harness. Does the light change color if you sweep the throttle?

That sounds like a good answer to me...

Jrichker, that is one of those "TPS enhancer" gadgets that claim to trick it into producing full throttle voltage at 3/4 throttle. Total waste of money.

That explains the no start problem. It probably died with the signal output stuck in the 4 volt+ range. That shuts off the injectors since full throttle on a cranking 5.0 Mustang EFI system turns the injectors off to clear a flooded engine.
