Okay so I found a few wires that have no ends and one wire tucks back in. My head lights are permanently on. My power in the car is run through a switch next to the ignition. It originally had a clutch fan but my fan are also ran from that switch. That explains the loose wires. Is there a diagram that shows me which wires are which? I intend to solder the wires and do a shrink wrap. Any suggestions or other ideas of how to do it right without replacing all wires?

Oil pressure is normal until oil gets warm. 45-50 at 3k and about 5 when at idol. Then when its warm it drops and when it drops, the car shuts off. Then it'll start right back up but the second I give it any gas, it shuts off. There no noise coming from the motor even when its running warm. I have boost, oil, and water gauges.

One thing at a time. First figure out why the car is dying. Have you run the diagnostic check for codes yet? Did you find and fix the boost leak?

I fixed the boost leak. And it was only throwing an o2 sensor with diagnostics.

Well, there ya go. O2 sensor readings are only used in closed loop (when its warmed up). Does it even have an oxygen sensor? Is it hooked up?

How does the o2 sensor work? I just tried googling it and I foud a lot but nothing really eccplains it.

I was just looking and I couldn't find my sensor. I don't think it has one. But I did find my oil leak on my turbo, and that there's a plate missing on my dowpipe that goes to my cat.

That's your wastegate, you can bolt a turndown pipe there if you can fit one.
That oil leak is not good, spray it down with some brake parts cleaner to clean it up. Next time you run the engine, check to see where the "fresh" oil is coming out of.
The lack of an o2 sensor might be whats causing it to stall. Is it using the stock computer? It should be mounted above the glovebox under the dash.

I found it. Its broke and one wire wasn't connected on it. I connected them and I'm waiting on it warm up. The check engine is is out but when I was letting it warm it came back on. I think it is a stock Ecu. It is fresh oil coming out of it but it only comes out when I give it gas.

Any ideas on the turbo fix ir is it just done?
