Default 1985 CORVETTE iat sensor

so i have an 85 corvette, and i just swapped the heads on it. while i was plugging everything back in i noticed a sensor under the intake manifold, but no connector in sight. i spent hours looking for it, until i gave up and bought a new wire harness. the new harness has no connector for it either. Am i making a mistake and that sensor was never connected in the first place? maybe the manifold is from a newer corvette?

There should be a wire for it it's one of those kind of important plugs. Did I you take the car apart because I always unplugged it and rerouted it from under fuel rail when working but with that said I can't swear if there is removable pigtail extension that goes to main harness that might be missing

I have to Agree with you about it being Hard Wired into the Harness I never recall Unplugging the Sensor any other than at the Sensor. but when searching for the Photo of the Plenum the Pigtail showed up several times.
