1995 240SX, What is This Box? And The Cable That is Coming From it?

Hello,

The car: 1995 240SX with an SR20 swap that I did not do.

So far, been unlucky with Google.

Essentially, while installing an alarm on my S14 I noticed the following black box by the accelerator pedal. It goes to a cable that has an eyelet at the end of it, but it goes nowhere.

Trying to figure out where it would go.

Right now, the air vents ONLY blow through the windshield defroster. I have reason to believe it is the actuator that needs replacing (I do see that part when I am under the dash) but my question is if this part may have something to do with it?

Thanks!
