I have just bought my car, 1986 trans am, lg4 automatic. PO had threw away the quadrajet and put a edlebrock on it and I have just bought another quadrajet to put back on it. So to the point. I have two electrical connectors laying on top of the intake that I thought go to the front of the carb. But after further looking into it, the one connector is a single blade/pin connector with a red wire and I can't seem to figure out where that would go. The other is a three pin which obviously goes to the front drivers side. Any help and knowledge on the wiring of these things is appreciated. Thanks!!

 

Here are pictures of 84 L69.

 

Single red wire should be to choke

 

Im guessing the second pic bottom left is the wire your asking about. That wire goes to a idle up solenoid. it has a plunger that will push on the the throttle arm to bump up the idle when the ac is on.
