If I read correctly, his stock harness is for a carb engine... not fuel injected.
I think you are going to have to do a lot of wiring so it won't really matter what engine harness you use. Any way you go you will have to make your own sub-harness to go from ECU to engine bay. You probably won't even need that 'preOBD to OBD-1' jumper harness since you will be wiring from ECU to engine bay pin by pin.
It's not impossible - just get the wiring diagram for your ENGINE and be patient!
Or did I read wrong?
Maybe he meant that it's a DPFI engine when he said 'efi carb'?
If that's the case then YES - go get your stock engine harness and convert to MPFI and go from there as suggested by 'knightsef-eg'
