Here's why:
* Technology in 1983: Computers in vehicles were extremely rudimentary and rare in 1983. The vast majority of cars and trucks relied on mechanical systems and analog controls.
* Engine Control: While some basic engine control systems were starting to appear in 1983, they were still very simple compared to the complex computer systems we have today.
* Digital Dashboards: Digital dashboards and displays were not common in 1983, further indicating the absence of sophisticated computer systems.
Instead of a computer, the 1983 G-Series van would have:
* Mechanical engine controls: These would include things like a carburetor, distributor, and mechanical fuel pump.
* Basic electrical systems: The van would have an alternator, battery, and wiring harness to power the lights, gauges, and other components.
