This is an example of the early '80s Government emissions compliance
thing...Just a reminder to replace your O2 sensor. Look under your dash,
driver's side, for a wire hanging down with what appears to be a white
plug. This plug actually contains a sliding switch. Slide the switch to
the opposite side with the ignition key in the "on" position, engine off
(KOEO). The light should go out once you start the engine. 
This procedure only applies to non-EFI trucks, those produced up to
8/83.
