Purpose of post: to provide general ideas to fellow tractor owners wishing to add lights, electric sprayers, even some high current accessories for short term intermittent use (think winches, jump starts).
I'll start with the high power preparations.
#1 good heavy duty wire, at Walmart you can buy power amplifier wiring kits (reason: high quality multi-strand wire with flexible insulation). I bought the heaviest one, 1600 watts, I think. It comes with an 80 amp fuse block. Replaced 80 amp fuse with 60 amp fuse. Winch has it's own 50 amp fuse.
#2 extra protection for high current wire. Farm stores sell spraying equipment bought chemical rated hose for it's abrasion resistance.
#3 power connectors. Farm store wanted $21 for a Superwinch power connector. Electric pallet jacks also use these connectors. At a local Hyster dealer I can buy 3 for $22. You don't have to be a rocket scientist on this one. They also sell rubber dust covers for the connectors.
#4 optional extra connectors for winch, jumper cables, future expansion needs (lights, radio ect).
#5 locate somewhere close to battery for master fuse block, small mounting hole will need to be drilled. Run wire through sprayer hose and route from battery to rear of tractor. Use cable ties to secure to factory wiring, hydraulic lines, frame, ect. The power connectors have 2 small mounting holes (#4 machine screws?). Use caution, don't drill into plastic fuel tank (thought about it on BX until I realized what the black plastic part was)
Now for time for some images:
