What are these 2 sensors?

Curious what the 2 sensors mounted to the drivers valve cover are. One appears to be a boost ,and three other a map sensor so to speak. One has a 2 wire red plug and the other had a flat 4pin plug

That is part of the boost control.

That shoes the one sensor as the boost solenoid, but doesn't say what the other one under my thumb is .

I believe that is all part of the boost control- there is a 90 deg. rubber elbow that goes on the (silver) barb on the piece in your hand and connects with a elbow that goes on the front of round piece toward the bottom of the bracket... hope this helps.

That other is the EGR control solenoid.
