Need help to ID a part

Hello everyone. I'm new on this forum

I need to identify a part and understand what an a/c mechanic did to my car a few months ago. Seems like he has modified the harness. Can someone tell me what part is in the picture of my 2009 cx7 and where it connects to? The engine stops if I touch those cables.

Thank you!

I disconnected the cables, the connector looks different, and now I have no car :(

These are pictures of the to ends that were connected
