Contact cleaner to the rescue! Power to the joystick and the plow moves. Cleaned the daylights out of anything electrical that could be cleaned. harnesses now almost sparkling and covered in dielectric grease. The fuse was fine, as was the fuse holder, but I buffed any contact points any way. The 9 prong connection between plow and truck is still a little touchy.
Unfortunately the left hydraulic cylinder, where the tube attaches, is now leaking. (was going to flush/replace fluid anyway).
The motor was whining/running hard when not moving anything and the two prong power cable was getting very hot. Melted a little on the plow side harness, probably need to replace (will get pics up later). Going to trouble shoot via the manual instructions.
Thank you all again for the help.
Back to researching and fixing...
