Mysterious plug in the engine bay

[wojtek]

Hello everyone,
I've changed the A/C system in my 97' TJ and found the plug. I've used the manual but I'm not able to recognize it, it looks similar to the power steering pressure switch plug; however, the colors of wires are different and a shape if the black part is slightly different (besides that, the power steering press. switch plug is on its own place). The colors of wires are green and blue/brown(pink?). I'm attaching pics for references. Do you have any suggestion what it can be?
cheers

I don't have a 97 manual but my 98 manual shows that as the high pressure switch connector for the AC (DB/OR & LG)(Dark Blue with Orange & Light Green). Did you put both high and low pressure connectors back on?

Where should it go? When I removed my A/C there were 2 connectors: one attached to the accumulator, second one to compressor.
