You are going to need to add the year and engine size. And possibly the calibration for someone to find you the correct VECI
I can't help easily but add that info and hope for the best
Your underhood sticker is gone?

The three valves you are looking at
I cannot remember the exact terminology but the 2 hooked together are tab and tab solenoids that run the thermactor
The other one is the egr solenoid or evp and regulates the egr valve
You have no veci to look at?
