EGR Help

I am trying to re hook up my EGR valve. The problem that I am running into is that all the schematics that I can pull up say that there should be 2 red tubes and one green tube. I have 1 red 1 green and 1 orange. All I really need are a couple pics if possible as to how to hook this darn thing up. Hopefully then I will get my check engine light to go out.

Also my temp gauge is skyrocketing, coolant level is fine so I am not sure why. Could it be that the fan is not kicking on, another reason why the check engine light may be going on? I really need to get this thing smoged so any help would be greatly appreciated.

no i have pulled codes yet. I called AutoZone and they said since it was a 94 that their machine would not work on their system. Where could I go and not spend pretty much anything to find out the codes? I have a feeling that it might not be. I litteraly just came in from looking under the hood and noticed several things that are not plugged in. I am starting to wonder if that may be the issue. My tags expired and the end of May so I don't have much time to clear this issue up.
