84 250R help

i need a wiring diagram for a 1984 honda 250R, honda made the 1983-1984 atc's pretty much the same design so if anyone has a wiring diagram for a 83-84 250R, if you dont have the wriing diagram, what i really need to know is what wire goes to the coil??, once i figure that out i need to know what is the best way to break in a new top end, i just bored it .20 over, and got a new wiseco piston and it cost alot so i dont wanna mess it up by doing something wrong...

please help,

84 atc 240r
