Random unplugged wires have no home.

[hypnotic]

I don't know what these wires are or where they go, they might not even have to be plugged in but I'm just making sure.

I'm not familiar with 93s, but I would venture to guess that's the EGR valve?

Did 93's all have "ATX compatible" harnesses? If so those are probably ATX specific plugs.

Don't know what the top two are, but the bottom one is supposed to be disconnected. It's like a tach output or somethingorother. I know it's disconnected on both of mine with no problems.

The top ones look to be one and the same, and look vaguely like an O2 sensor. Isn't the bottom one the SPOUT? Either way, you can tell that 2nd one doesn't belong anywhere, on account of how dirty it is.

the one with the red on it looks like it is for the intake runner control

I cant fully tell from the pics but, I remember having some dissconect3ed wires there and one ended up being my under hood light. Do you have an after market hood of does your underhood light not work? Ifs so that might be one of them.

the first 2 are for the EATC, for the CELO sensor on your lower heater tube

That's right ... I remember now. The EGR is much lower on the harness.
