Can anyone tell me what this green wire is?
While replacing my heater hoses I noticed this green wire that had been pulled out of the engine harness, cut, electrical taped, and tucked down behind the wiper motor. This is right before the harness passes through the firewall. I can't tell what this is, or what effect it might have been having (my car is 2 months on jack stands replacing, fixing, tightening, cleaning and demystifying my engine bay).
Wiring diagrams for the engine harness show green for the IAT and crank angle sensor, but I'm not sure that the car would have ran without either of these, and the ECU wasn't throwing any codes. Weirdly, I get continuity between this wire and every connector on the harness, and also any point on the engine block (though not the chassis). I haven't figured out how that is happening.

Yeah that's an aftermarket wire someone added in. You'd probably need to put in a ton of effort to unwrap the harness and see what it's tapped into, if the car is running and driving OK just tape it up and move on.
