 How much different is a 1980 4.5SEL electrical system than 1977 & 1979's ? Will the schematics be close, and are there many newer electrical parts on a 1980 ???

There will be differences in the engine wiring for emissions, and there will be a difference in the climate control wiring if one or the other has manual climate control or automatic climate control. 

Lighting will be the same, assuming both are U.S. models.  Euro models are different. 

In addition, depending on what electric options the car has will add or subtract to the wiring of the car.  Electric windows, heated seats, (front and/or rear), electrically adjustable rear seat bench, sunroof, in car Webasto heater, ABS, fanfare horns, electric antenna, radio, rear reading lamps.

Thank-you ~~~
I ask because I found a 1980 electrical troubleshooting manual very reasonable. I think it may have more photos & repair info than the 1975-79.
