I was recently posed with the same problem. I used flexible rod sections (which screw together for added length referenced in the above reply) and was able to push it through between the compartment for the head and the hull all the way into the cockpit sink area. After pulling the wire (10-2 AWG) from this location to the frig., I ran the wire into and across the bilge then back up the starboard side using the same technique fishing from the breaker location at the helm seat. I connected to the frig breaker there and the frig now works like a charm. I must admit, this took some time, but with help it's doable. What was FW thinking about when they engineered a 14 wire to run the frig? Should have been a recall but after calling a FW tech, he said there were no problems with the way it left the factory
BTW, I purchased my wire online at Genuinedealz.com. Best wishes.
