What're these connectors?

I was under the hood today and I noticed 2 connectors unplugged, and I am not positive where they go. Any ideas?

They are located directly behind the belt tensioner, and go into the bottom side of the black smog pump thingy.





Thanks!

I didn't think my car CAME with A/C. Could you buy a camaro from the dealer without the AC? That's the impression I was under...

Looks a little like your car may have came from the dealer with A/C in the past (unless you bought it new without it) and someone removed it. The big pulley on that side where the connector is is where the A/C compressor should be, and is the optional A/C delete pulley. That would be some connector for some sensor that hooks into one of the A/C lines, just like the one I disconnected today.

I would have to go with A/C wiring also. From the pic it looks like you have a standard (non A/C) heater box. You car probably was ordered without it. GM just put the full wiring harnesses in cars to save time and money. When I switched from a 700 to T56, I found the clutch switch wiring taped up under dash by the pedal area.

The round one is the a/c pressure switch that would normally plug into the rear of the a/c compressor and the other is for the compressor clutch.
