I ordered the helms manuals (factory service and electrical troubleshooting) for my 1990 RS, but they won’t be coming for a week or more, and I was wondering if anyone had scanned the fuel/emissions section and the electrical section (not really the diagram section, just the section called electrical). We’re going to have halfway decent weather this week, so I want to get some work done on my car, but since I’m waiting on the manual, I can’t really do much until it comes. I saw the scan that I believe ryank did, but that’s the 92-93, and my problem there is I need the test info for the 90-91 ecu (non-OBD) relating to the ignition and the fuel injection system, or are they the same for both ecus? I figured they wouldn’t be since they’re different connectors and standards. Anyone ever scan these? TIA
this link is the 92-93 manual… 
does it make that much of a difference?
ya, I’ve seen that link (which is the 92-93), and my problem is the ecus are a bit different, at least the connections are, and I think the way they operate may be a bit different as well, and the ecu is what I need to test, so I need the 90-91 info. Oh well, I’ll just have to wait I guess til my manual comes. Thanks anyway!

well, ya know. 
i’ve used this thread to find it when i’m at the indoor place i work on my car, 'cause i’m too cheap to print the whole thing out and the computers here have web access but no cd-rom drive.
