The 4WD indicator switch is illustrated just to the left of the fuse box in the 1980 Wiring Manual.  The dashed lines mean the switch and indicator only apply to four wheel drive applications.  Check the engine compartment firewall for a two terminal connector that has white and black wires running down toward the T-case.  The T-case harness maybe dangling or may have been removed and discarded.

In other words... if people learn by making mistakes, by now I should know just about everything!!!
