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?

Smog and EGR are separate systems. Just because you delete smog, doesn’t mean you need to delete EGR.

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?

Stuff is pretty easy to look up at the library on Alldata
Is it a Cal car or 49 state?
I could try to find a vacuum diagram for a generic one next time I go ( your VECI would be specific for your calibration )

There is a way to order one using your vin I believe
I will check and see what I have here in the way of what you need because a truck or crown vic has about the same exact setup

The lines that you disconnected, did you plug them up (cap them off) ?
