in between the thermostat and water temp plug there is a stud in the intake manifold and two plugs that i gues plugs into whatever goes there this a 91 305 tbi can anyone help me????

 

If I'm thinking of the same intake stud you're seeing, there is a brace bar that should be held onto that stud and onto the back of the A/C compressor with nuts.

There are two two-pin (I think) connectors for the AIR diverter valve that could be sitting near there, if someone disconnected it (e.g., if they removed the pump and AIR tubes and hoses). Also, I think the A/C compressor has two connectors...

 

i have all the stuff plugged into the AC and the brace is there the plug wires are pink and black anyone have these on there car
