How do you konw wich plugs go to wich injectors? I just put the engine back in the car and it has a miss, so im just trying to find any other possable problems before i buy another opticrap. I rebuilt my first one with msd cap and rotor, it had 100k on it but worked fine. I had a coolant issue right away and am pretty sure it got some coolant on it.

It does not matter as long as you put them on the left and right bank. It would be pretty hard to mix that up with the way the harness is formed. 93s are batch fire and don't use individual numbers to the injectors.

So does that mean that the 4 sets of plugs from the wiring harness are interchangeable? Its easy to see where they all go, but the 8 plugs come out right next to each other in the 4 corners basically. So i kow the 4 sets of 2 plugs are in the right spots, i just dont know if they are on the right injectors since theyr coming out of the same spot in the loom.

Does this make any sence?

Like Shbox said, with batch fire it doesn't mater, as long at you get all the bank 1 connectors connected to the bank 1 injectors and all the bank 2 connectors connected to bank 2 injectors.

There should be two rows of 4 plugs each. It should be fairly plain which row goes where by the way the harness is molded. Any plug on the row can go to any injector on that row that it will reach.
