I would not change the sensors until you have refurbished the harness...you may be getting false signals right now as a result of the bare wires making contact with each other.

If you are talking about the connection pieces, I'm not sure they are available...I salvaged mine as best I could and reused them. Haven't had any problems yet, and I did the fix about a year ago.

Once you reinstall the new harness...verify that the connections are correct. After that, assess what still appears to be problematic, THEN go ahead and decide to replace the offending sensors.

The oil pressure sensor runs about $70. FastLane does have this.

I didn't have to replace my oil level sensor, so I don't know the cost. But FastLane should have that too.

Contact Phil at the FastLane number on this site. If you can't find it, Phil will get you set up.

But as I said earlier, let's get the wires back in shape first.
