Can i get an engine part identifacation?

[FlaAveo5]

Can someone tell me what is the small bundle of wires, that is right above, and to the LEFT, of the coolant reservoir tank, on the fire wall,it is kind of attached to that small black 'canister', almost sitting on top of the coolant reservoir. What is the wire bundle?

It has like 4 wires going into it. It is attached with a simple plastic clip, to the metal part, that is attached to the firewall. The black 'canister' is right above the coolant tank, the part I am talking about is the small wire bundle with 2 white wires in the top of the bundle. The wires are not damaged, just the cheap plastic 'hook' that holds these to the car. The car still runs fine, but I rather have it attached correctly, or tell me how to attach this plastic piece back to the metal piece on the firewall.

I tried to superglue it back on, didnt work, I have Gorilla tape holding it on now, doubt it will hold long. Going to go to Chevy sometime this week, but if I knew what it was, I could call and ask to order the part, or look up the part on Rock auto and buy it.

I dont know if it is a super important wire bundle, going to a computer, or just the wiper relay, so i cant look it up. Anyone?
