All OEM related XJ specific tech. Examples, no start, general maintenance or anything that's stock.
I reread, and the airbag light coming on when you turn the wheel sounds like the clockspring itself. The rest, i dont know. Too many questions.
Is the TPS connector properly seated? Did they replace the wiring, or just the connector? Are the pins seated in the connector and not backing out? Are they clean? Like PatHenry asked, what brand TPS? Mopar is best. Anything else is questionable. Why did the PO disconnect the oil pressure switch and leave it hanging in the first place? Where is it? How was the PO monitoring oil pressure? If they added a second switch, where is it? I can only assume there isnt one as the gauge isnt working. Lots of questions, but if it were mine, id be checking everything the PO did. That missing oil pressure switch connector is bugging me more than anything. Dont drive it until you have a reliable means of monitoring that.
So in other words, too much trouble to deal with and the P.O. wanted a new(er) vehicle.
Can you get the sender to plug in or is it too short? Did you check to see if there's extra slack either bound up in the wiring sleeve or by re-routing the connector?
Good news on the TUPY head -- it doesn't look like it was "just" put on or anything, does it?
I agree with fb97xj1 that the disconected sender is suspect, but until you get it connected and see what your oil pressure is, I can see it being as simple as the plug got dislodged during an oil change and the P.O. didn't care enough to correct it -- it is odd that it isn't as simple as "plug it in"... the factory wiring to the factory location would obviously have been long enough. (If you're wondering why I keep asking)
If the oil sending unit grounds out, it will simply peg the gauge, it has zero interaction with the engine control stuff.
You can always grab a mechanical test gauge for oil pressure (maybe a good idea anyway since who knows if the sending unit is even functional) to verify oil pressure. It needs to be no lower than 13psi at hot idle and no more than 75psi. Normal operating range is about 28 psi at hot idle and 60 psi under load (in gear and driving).

I don't think this the orginal engine because the block and intake manifold are painted black and the valve cover and fuel rail is red
Eh, that doesn't mean anything - whoever installed the TUPY head probably painted the cover and fuel rail while they were out. It's a lot harder to paint an engine block. The fact they are NOT painted I think makes it more likely the block is original. Which is fine, 230k is nothing. My Dad's 94 had 400k orig miles on the engine (which still ran perfectly) when he retired the Jeep.
So the location for the oil switch on mine is totally wrong for a 2000. It should be located close to the oil filter and that explains why the plug doesnt reach.
Should I switch out the switch with one that will fit my plug?
It's possible a P.O. relocated the sender and used an aftermarket gauge -- why they'd relocate it is odd, but it is kind of a pain when changing the oil filter.... speaking of that - get rid of that "orange can of death" and put a quality filter like a WIX/Napa Gold or -any other filter than Fram-- on it as soon as possible.
No clue what it is. Only has one pin on the inside
Something looks fishy... your oil filter adapter is gone the sensor you have looks like a oil pressure dummy light due to one wire(?)....Could they of swapped motors to a early year on that has the dummy light the connector you show looks like the one on my 2000. I would bump motor over and see if oil comes out of the hole you removed the sensor from if its oil that's the pressure switch. I'm no expert and know more about 67 mustangs as only been messing with XJ for 3 years....just a thought.
