Default AC Delco GM ST-200 Diagnostic Tune-up Center

Hey, I picked up a project recently. As the title says, an ST-200 analyzer set-up. It needs some going through. The version I picked up doesn't have the rolling stand with it (no biggie to me). It's also missing 1 test function which falls under the "Economy and Smoothness" settings, the "Air/Fuel Ratio". I was thinking it's due to the fact it was used at a marina to tune up boats, no tail-pipe sniffing. The bummer part for me is that it's missing the main connection harness and there weren't any manuals. The main harness connects to the octal plug and has the fan-out to connect to the engine, starter, etc. I was hoping that I could get a lead on those items from the Supercar brain-trust. I am perfectly capable of building the harness, I just don't know what connections are at which pin or the wire gauges. If someone has a harness and they wouldn't mind buzzing it out, that would be great. Maybe someone has a manual they can scan?? As always, I'm grateful for any info/leads.
