what is that connector

Im having trouble finding out what the two connectors are belowe the BVSV valve on the thermostat houseing. Also there is a plug behind the power steering bracket. can any one help me find out what thay are. I have had no luck finding them. Thanks for any help that you can give.

Turbo? The plug behind the PS pump is the oil pressure sender, as for the christmas tree (thermo housing) the two below the BVSV are the fan switches. The E-fan is blue and on the bottom and the aux fan is white and in the middle
