Unknown Plug Connectors on 87 4runner R???
 

Couple plugs recently found that are not connected. Trying to find pics and descriptions but hard to follow where wires lead to. Any input greatly appreciated.

Directly under intake manifold. The connector under the red wiring with thicker gauge wire and the connector to the right of that.

this one is hanging but held up by a bracket that seems to be on the transmission but no other lonely hanging wire found :(

The one under the intake may go to the idle air control.

The single wire to the tranny area is likely the 4WD drive indicator switch on the passenger side of the transfer case, near the top.
