I will pull it apart and get back with you later today. I also will review the others posts and wiring. I might end up re-wiring the car at this point!Where does your fuel pump relay under the seat tie into the main harness? Are you able to trace that back to a connector?

I think your observations are correct based on what we have found thus far. For what it's worth, I think the engine has been out of the car and maybe it's a different year engine too -- maybe I'll pull the engine starter and see if I can get numbers off the block to determine what year block it is. Although I don't think it matters what year engine is in the car, does it?I wonder if just getting the correct 1993 engine harness with the FP relay in the bay would solve all your problems.
My assumption is this. For some reason the previous owner removed the original engine harness and installed a 1991 engine harness with a 88-90 O2 sensor harness. That may have toasted the ECU. The tried to rig the fuel pump with the jumper wire because whatever they did with the underseat wiring did not work. Who knows where it runs off to.
I think those 8 wires are C230 and C297 courtesy door light switch.
Reason I say that is because the main harness running to the rear of the car has 5 plugs according to the diagram. Two are the 12-pin, one is the round 8-pin.
The trans 8-pin black is a separate harness.
Is the door switch hooked up? Or os that cut too? What about the power Windows/doors? Those functional?
I need to look at the diagram in a bit. What about the pass side? Anything disconnected or cut there?
I don't that this car has any courtesy lights that work. It's got a factory sun roof and the wire is still up in the front center of the roof where the chrome light is normally located, but it's missing. I don't see that color combination of wires in the left kick panel.C297 LH courtesey light looks to have 4 wires.
And two light green/yellow

I am still puzzled by the fact that we think the interior harness is from a 93 given the door switch wiring, but if that is the case, then why is the fuel pump relay (which is part of the interior harness) under the seat in this car when it should be in the engine bay?! I wonder if someone in the past re-wired part of the interior harness.
