MF 240 Wiring

[bigbill61]

Bought a used MF 240 about a week or so ago. Someone has hacked the wiring. Horn blows when flashers are on. also they wired 2 fans onto the canopy. There is no switch they just run all the time. I know i can just wire a switch, but i would like to have it done right. Does anyone have a wiring diagram for this tractor that they could send Me. Also please explain all the symbols as I am electricly challenged. THANKS
