Hi, me again...
As I have made painfully obvious I am looking at doing one of two things to my '85: EFI swapping my existing 2.0 engine with original head, or swapping in a 2.3 with EFI. The end goal is fuel injection and I'm not too worried about how I get there.
The thread linked above explores the first option, and it is still on the table.
This thread explores the second option, using an engine I have been offered locally (for too much money, but if it gets the best result, maybe it's not too much money).
This engine is a 2.3 EFI that has never been installed in a vehicle, supposedly. The story is that it came from an Exxon fuel additive dyno test lab (this really is a thing, and these 2.3 engines are the specific engine required for the industry standard testing). The current owner bought it over 15 years ago, it has not ran or been turned over at all in that time, and it supposedly only ran for 11 (eleven) hours total since it was built. I have no way to back that up, but I don't see much reason to doubt it either.
Facts:
Please take a look at the following photos, and let me know what you think I will need to add to this engine and harness to get a usable result. My exhaust manifold in the truck currently has an O2 spot already, so I'm hoping to use the existing manifold. My 2.0 has a brand new clutch and flywheel on it, so those will be transferred onto this engine, and I will reuse my starter (although I want to upgrade to a PMGR one off a newer year eventually).
Does this harness look like it can plug into the body harness of a 93-94 as-is? Specifically thinking about the grey and black rectangular connectors.
I have numbered the harness connections in a couple images. I suspect that #1 is the oxygen sensor (HEGO has 4 wires), #2 may be a ground, #3 is the ECT which mounts in a heater hose, and 4/5 are obviously the connections into the body harness which then find their way over to the ECM. Any corrections?

Facts:
- It is wired with the engine harness, not all the way back to the ECM connector, but all self-contained engine bits of the wiring seem to be there. I would be able to complete the harness with a junkyard donor truck and some "quality time" with a utility knife, I suspect.
- Known missing: fuel rail, IAC valve, thermostat housing, alternator (it may have never had an alternator installed, but the side-mount 3G bracket is there).
- No A/C or P/S brackets or parts, which is fine for me, since my truck has neither. It also does not have a smog pump, and probably never did either.
- I stupidly did not think to make a note of the full part number on the front of the timing cover, but it is an F5 number, which puts this as a 1995-revision part.
- It uses an FL400 instead of an FL1A filter, so it is definitely newer than 1994 (last year for EEC-IV), however...
- It has the crank position sensor inside under the timing belt cover = EEC-IV
- It has the ICM mounted on the intake = EEC-IV
