My old 2000 Kodiak had a bracket that was supplied by Warn for the cable to connect to. The winch cable went from the winch down to the plow bracket and straight back up to the bracket which fit over part of the bumper. This now only wore on the roller flair head but also the cable. But in around 15 years of plowing with it I only snapped one winch cable once it started to wear and fray. I also had to replace one flair head where the winch line started to bite into it.
This was on a under the frame mount for the plow.
Now on my front mount plow on my 2016 the cable goes from the winch to a area around the plow piviot where it goes through a pulley and then angles back up to a strap that is in the plow kit that wraps around the front rack. In a couple years of plowing I haven seen any problems but I might figure out a steel bar to fit across the front bottom of the rack for more strength than the tubular rack to attach the winch hook to.
The plow kit came with a fiber pulley that was attached closer to the machine but I ordered the pulley kit that fits further towards the front of the plow which decreases the angle of the cable to it.
You can see the strap around the front rack in this picture. I just used some mule tape that I had right at first but went back to the factory strap.
