The first pic - I'm assuming that you are under the car on driver's side. Look for male spade connector sticking out of really greasy oil pressure switch and funky round terminal on oil pressure sensor (both somewhere near oil filter). Harness should(?) go towards/up past alternator and power steering pump where it becomes part of alternator and Power Steering harness. Once past the PS pump, travels back toward firewall and then to connector in third and forth pics? Seems like they are all blue , green or combo of both, as I remember.

Oh wow just noticed the date of op. nevermind

I'm pretty sure the last one goes to the ac compressor.

Edit: Wow, I just read the end of #2's post.
