Out of Nowhere, ABS INOP light on and LOW TRAC and BRAKE light flashing

This morning when I got in my car to leave for work, I noticed that my ABS INOP light stayed on when I started my car (it usually comes on for a few seconds when I turn my key on). Then, when I started driving, my LOW TRAC and BRAKE light started dimly flashing/flickering and the ABS INOP light stayed on this whole time. Sometimes, when I stopped at stop lights, all three lights would stop flashing, stay on for a couple seconds, and then turn off. Once I would resume driving, the ABS INOP light would come back on and the LOW TRAC and BRAKE lights would start dimly flashing/flickering again. Last night, I only did two things with the car. I had the rear end on jack stands and the car in drive briefly because I was listening for rear end noise, but I didn't touch anything back there. The only other thing I did with the car last night was clean the engine bay a bit. The only thing that I did under the hood that wasn't just wiping stuff was I removed the nut that holds down two or three black wires over by the red plastic positive battery thing. I put it back exactly as I found it. The only other thing that possibly comes to mind is that I took the cap off of the brake fluid reservoir to better clean it, but that's it. Does anyone have any ideas what could be causing the lights?

First and foremost, make sure your third brake light bulbs (in the spoiler) are still functional. No joke.

I figured it out! I noticed that the underhood ABS relay was clicking like crazy so I immediately started looking at the ground that I messed with last night, and sure enough, I didn't tighten it down all the way! I snugged it down, and all is well!
