¿ Engine Wiring Harness - 1981?

[Vader]

I've got my hands on an '81 350, E4ME, TH-350. Some previous occupant found it necessary to "alter" the engine harness with wire cutters and vinyl tape. I'd like to rectify this Goldberged mess. The new TPS is set correctly, MCS is intact but not duty-cycling. No DTCs. The ECM is active and O² is new. I have a connector that I believe was for the AIR port/divert solenoid that is just hanging in space. It is the same WeatherPak connector used for the MCS, and you can guess what I'm wondering...

Any idea where I might download a schematic for an '81? I've traced the wires to teh WeatherPaks at teh bulkhead and I have continuity. Any ideas from there to the ECM? I know the '81 ECM was somewhat of a "loner", and is very limited, but a roadmap would be nice to have, or at least some directions.

I bought a copy of the wiring from Ecklers about $15, not sure if it can be downloaded.

Thanks for the info. I was planning to hunt down a Helms manual on eBay or at swap meets, etc., but it appears that I'll not be able to wait. I'll check them out.

O.K> I got my hands on an engine harness diagram. The burning question is regarding the "extra" two-wire WeatherPak connector I have. There is no A.I.R> on the engine any more, but I suspect that the spare (gray plastic) WeatherPak was intended for the AIR divert solenoid. The problem is, a previous owner hacked the wiring, and spliced this connector to two different color wires (cut, twist, and tape - nothing but the most professional care for this one...). Anyway, I understand the AIR connector should have a blue and a brown wire in the connector (which it does) but the connector was spliced to a orange/black and light blue wire.

For those with the AIR system still intact (1981 only), is the aior solenoid connector gray, as this one is?
