I just got my EFI harness and am in the process of checking off all the connectors so I know where they go before tearing off the old one. I was trying to follow the wiring diagram in the FSM, but the only one I could see was one for a turbo. (attached). I'm a little concerned that I might miss something that is no longer present due to the fire. Anyone have a similar diagram for a N/A? (it's an '88 N/A ). I've looked through the PDF several times, and can't seem to see one. Seems strange they would have one for a turbo with A.B.S., but not an N/A. I assume the only difference would be my harness would be missing the connectors for turbo and ABS. the screen shot is from page 115 of the wiring diagram pdf.

Thanks in advance.

 

There are only two pins that are really different, as well as some of the wire lengths/locations, but other than that, the ECU wires are very similar.

 

I think I'm getting it. Been standing over the engine bay with the "new" harness laying nearby. Just a couple of items around "ground zero" that are melted or burned up and I think I got a handle on which is which. Only one that seems to confuse me now is the O2 sensor connection. Old one was melted pretty good, but I can tell it was green. diagram shows a single wire, and looking at the harness, I don't see a single wire in that section of the harness with a green connector.

There is, however, a connector that is black taped to a single wire. Wonder if the previous owner had a replacement O2 sensor with a different connector. Other than that, I believe I've found a home for the rest of them.

BTW, do you recommend removing the rat's nest for harness replacement? I'd like to avoid that mess, but maybe it looks messier than it is to remove.

 

Pretty sure I found everything. Found the O2 sensor connector. It's white/cream, not green. I swear the one on my old harness is green, but maybe it's just overcooked
