1990 WIRING HARNESS QUESTION​

Engine Harness (passenger side) Dash Harness (Driver side) are two independent harnesses with the exception of two large round connectors under the brake booster. Any one have a wiring diagram for these plugs. What do they do? If you go stand alone engine control and get rid of the engine harness and computer what happens?

If you mean get RID of the engine harness and computer, what happens, you will have to describe for me what "stand alone engine control" means. I am well into understanding exactly how Ford's EEC-IV works, and what wiring is absolutely mandatory, but have not kept up with today's aftermarket developments. I'd like to learn, though.
