Unknown electrical component

My son hit a dead opossum in his aging 2004 pontiac vibe. While tucking the fender liner back in place, I noticed this rectangular box hanging down inside the left front wheel well. I have it temporarily zip-tied to the frame. There are two wires coming out of the bottom. It appears it was originally bonded to the rusted bracket in the upper left of the photo. Can anyone tell me the name of the component and its function? Thank you!!

This picture shows a faint glimpse of a denso part number..

Looks like the radiator fan relay. I googled part of the number "Denso 3560" and found what looks like it:

That is impressive!
Here's a US source:

It's actually a resistor, which makes more sense since there are only two terminals and it looks like a big ceramic resistor.

That was my first thought also! I had one of those infamous ceramic resistors on my 1972 Plymouth Duster that would fail every now & then

I'd forgotten about that ignition resistor on my '73 Dodge pickup. I kept a spare in the cab.
