NOt a pathfinder owner either, but I did the same on the Hilux. Down the passenger side chassis rail, on top where practical. Whole length is in another protective (slightly) layer of corrugated tubing. Rub points have some 19mm Poly garden hose for extra protection. 50amp Maxi fuse at the batt to stop the cable from welding itself to something should it get disturbed.
Just make sure your anderson is out of harms way, so a dropping off a rock ledge or a stray rock from the wheel wont hit it an destroy it. A saw a mates install and he was "advised" by the autoelec to pop it on the bottom of the towbar. It's well and truely in harms way and whilst it might sound like a remote chance a flying rock will hit it, if you are 4x4ing and you drop off a small ledge onto your towbar, smash goes the anderson, and the power to the CT!!
On a related topic, can anyone cast an informed light on Brake controller location. I understood it must be able to be operated by the driver, and as such, passenger side of the console was generally considered a no-no? other than common sense, is there a legal requirment in any state/territory/fed law/rules.
