What are these two sensors?

[shoccwave]

I'm trying to swap out these two sensors that were originally on my car to the new engine I put in but I'm just curious as to what they're called. I'm almost sure the top one is the TPS but I'm not sure about the bottom one.

Not familiar with NT, but the Big one should be TPS and the small one is for ISC motor/iguess/......

TPS (throttle position sensor) top.
IAC (Idle Air Controller) bottom.
