Disabled EGR...what to do with vacuum lines to and from solenoid?

I got a new prom with EGR disabled on it, and I just want to throw away the solenoid, but I don't have the time to take apart the intake and get rid of the EGR itself. What should I do with the three lines going to the EGR solenoid? One exits toward the back and goes around to the cruise control and vacuum reservoir, and then two come off the front - I think one turns around and goes to the cowl for some reason or another, and the other one IIRC goes to the EGR valve. I would appreciate it if you guys could tell me what I should do with these. Thanks.

Well the back one feeds vacuum to my vacuum reservoir and my cruise control, so I assume I should hook it back up SOMEWHERE, I just dont know where. I dont want to screw something up, because I dont understand engine vacuum and how to control it or whatever, where there should and should not be vacuum or whatever.

is this all part of the EGR?

connection #3 goes under the TB and the connection #4 goes to the charcoal canister I think....can all this be done away with?

Can all of it be done away with? #1,2,3,4?

Cap off the lines that only go to the solinoid, for the one that goes to the cruise too, get a 90* rubber elbow fitting or straight splice fitting (Vacutight, from most any auto store) and run the line to the CC. Don't throw away the solinoid, valve and associated parts, you never know when you might find yourself having to get emmissions tested and that stuff can be hard to find and expensive.

If you don't have a charcoal canister can you just plug them all? Will the cruise still work?

As long as there is a vacuum source for the cruise it will be ok.

Because I broke two of the Vac Lines for my EGR, and it looks ugly with the tubes I am using.

blocking the vaccum port at the throttle body should be fine.
