Default Sensor question

Can someone tell me what are the two sensors in the front of the intake manifold? One has like a fuel injector plug on it, and the other has a two wire plug. Thank you, Joe

2 wire sensor circled is the Coolant Temp Sensor for the ECM.
Brass unit to the left ( with inj plug ) is the cold start switch to operate the cold start injector used on 85 -88 TPI

One is the CTS - Coolant Temperature Sensor. It connects to the ECM.

The other is the cold start switch (the one with the fuel injector looking connector). It turns on the cold start injector while the engine is cranking. It's a thermostatic switch and opens after 8 seconds of cranking or when the coolant is hot.

Thank you, I thought the one had something to do with the cold start but didn't know what. Joe
