When checking the ACC unit tracing why the compressor was not engaging found the wires to the compressor disconnected. I need you help in connecting to the compressor, ( 2 wires - one blue/green and the other brown(ground). Looking at the compressor I see an upper & lower coneectors, does the (blue/green) go to the upper and brown to the lower or vice versa.

Thanks

That should just be going to an elctromagnetic clutch.. if there is not difference in distance to the connectors which corresponds to a longer and shorter one... it may not make any difference which is hooked to which.. try it one way ( random ) and see if it works... if it really made a difference they would usually have different connectors which could not be hooked up wrong...
At worst it will probably work one direction and not the other....
