WTF is wrong with my EEC??? Need Serious HELP!!(long)

I've been having problems with my EEC ever since I got the car about 6 months ago. If you search my previous topics, they've all been related. I pulled 10 codes from it when I bought a code scanner. They were 51, 22, 53, 54, 35, 67, 81, 82, 85, 95. I replaced the ECT, and a few of the codes went away for a day and then came back. My TPS is one example of what's going on. I went to set it today and it read 5vdc from the green and orange wires! If I moved it, it didn't change. Oh and I could only get a reading if I grounded the multimeter to the grounding strap from the motor. If I used the black wire for the TPS, I got no reading at all. I replaced the TPS, but it didn't change anything. The only noticable problem that I have is that behind the intake in the wiring from the white 10 pin connection, there's an orange wire that someone has stripped the end off of and it's just sticking out of the wiring. It doesn't go anywhere. I measured it's voltage and it read 0 with the ignition off and 3v KOEO. I don't know who supposedly converted this car to Mass Air from Speed Density, but I don't think they did a very good job. It doesn't idle right, it won't start hot, and none of the voltage readings are correct. After it warms up, it seems to run alright until I shut it off again and have to wait 20 minutes for it to start again. How can I find out what EEC I have? Any good wiring diagrams out there for it? I have no idea what else to do and my wife is pissed because I can't get it running right and keep spending money on it with no luck. The cap and rotor are 6 months old, new fuel pump and new fuel pump relay, new TFI module, no smog equipment or canister purge. The rest is in my sig. Any suggestions?
