In this pic I cant find where this vent tube runs. can someone show me with a picture or explain because I cant find it for the life of me. Its the evap tube coming out with the fuel lines. Took it off when I did the FPR.

In picture 2 I have this green wire coming out of the injector harness on the passenger side up by 1 &3. Its bare and may cause a problem. Anybody know what it is for and where I need to put it?

Lastly I have this blue plug. Its attached to the one on the sensor that's on the cold air intake shown in pic. I took it off when I changed my opti last week and cant find what it goes too.

Please help me with these 3 issues. my car has been running with a miss and really low on power since changing the opti. suspecting one of these or maybe crossed/burned plug wires. tune up coming next week. but I still would like to have these put up where they belong.
I know I'm dumb for forgetting where I took these off from. My mom is blonde and I'm afraid its rubbed off on me in this instance.

1 - Looks like the EVAP tube that runs around the front of the intake under the throttle body. From Shoebox:

2 - this is Shoebox's photo of a 95 engine harness, virtually identical to 94. The only wires that extend beyond the #1 and #3 injectors are for the ICM, coil, MAF sensor and temp gauge sensor. Neither the MAF, coil or ICM have a green wire. The temp gauge sensor has a single wire, but not sure what color it is. The photo is not clear. Is the bare copper section completely broken off and sticking out of the plastic harness casing?

3 - what color are the wire to the blue connector? Looks like it's for the coolant temp sensor in the water pump housing. Those wires would be yellow and black. The inlet air temp sensor connector on the elbow is similar but connector is gray plastic, not black. Those wires are tan and black.
