How does a person reset the "Maintenance Required" light
on a 92 Wrangler 4 cyl?

The only way to reset the light is with a diagnostic scan tool, such as the dealer uses (DRB2 and DRB3). My dealership charges $39 for this service! I'm not sure if the aftermarket scan tools have this function. The light is set by the engine control module to come on every 82.5k miles to remind you to replace the oxygen sensor. The only other thing you could do is to remove the bulb or put a piece of tape over the offending light! Hope this helps, good luck.
