Hey all
I was loosening the distributor to set timing and noticed this unplugged 3-wire connector. Couldn't see anything that could connect to it. Anyone have any ideas? looks like black /red striped/white going to it. Pretty sure I didn't disturb it during the distributor work, Looks dusty like its been this way for a while. Thanks .

 

4bbl car? I'm thinking the blue/green weather-pack is for the MAP or barometric pressure sensor? But admittedly the computer controlled Qjets arent really "my thing". If your car has been changed over to a non-feedback carb, and vacuum advance distributor, the sensors could have been unplugged since they werent doing much anyway.

 

Thanks Drew, yes I believe its the original 4bbl Computer Controlled quadrajet.It's a Van Nuys factory car, sold new in northern Calif so not sure if thats a clue. Gonna find some schematics and check it out some more,Thanks again

 

Yup, looks like for the baro sensor.

That would originally have been on the edge of the windshield cowl, about right above the pass side valve cover.
