Power cable in 02 Chevy Suburban - where does it go?

I noticed on my 2002 Chevrolet Suburban that there’s a cable under the bonnet that’s unplugged and I’m trying to work out where it goes. I’ve included photos of it and where it runs. There’s no corresponding unplugged female connector that I can find anywhere.

I bought the vehicle fairly recently and as far as I’m aware it was unplugged when I bought it. The SUV has no issues except it occasionally gives an ABS warning light — I haven’t yet looked into that problem.

Does anyone know where that cable should be plugged in? Let me know if I need to provide any more info.
