Couldn't view the pic. but wonder does it look like a factory wire?
If so, I'd check a wiring diagram. I did a quick search and came up with this link

I don't have any experience with ABS but I'd imagine if it were an ABS wire, the ABS lamp should be illuminated in the dashpod indicating there's some malfunction. You should be able to disconnect the ABS system by pulling the fuse if you were worried.
