I also did the same. I zip-tied it to the part of the chassis where the guide rod mount bolts to (there's a small protrusion) to prevent it from being snagged away.
Routing it down is easy, I inserted it between the exhaust heat shield and the car chassis, behind the shield. The new battery came with the L shaped rubber hose so I just got the remaining 1/2 ID tubing I had and just inserted the L shaped hose in there (it fits snugly).
