Yeah it's a rear lower tie bar. And I'm not talking about the actual brake fluid lines, I'm talking about the ABS wires, they're bolted to the subframe and the control arms with little metal brackets, and if you put the tie bar on then it's impossible to remount the brackets that go on the subframe, so I just had it zip-tied to the tie bar.
I figured out how to get rid of the brackets though, so I'm all good, it looks a lot cleaner. Thanks for the response though.
