Any help would be appreciated. I have a 86' 4runner 22re. I have got most of the wires back to where they belong ,but there is one I can not find a home for. The wire is as long as the injector wire and has a conector the looks like the injector ends but is a light blue instead of white. Can anyone tell me where this goes.

 

A pic would help alot.

 

A blue connector like an injector of that vintage should be a bosch type with a spring clip then try the auxilary air valve under your throttle body, its the heater for the valve.
