JD 318 wiring - help

[KDOregon]

My JD 318 shredded the front PTO belt and took out the wiring. I'm left with a blue wire hanging from the bottom of the PTO, a white wire up at the top right (passenger) side that was completely shredded. Also a blue/purple wire coming of a rectangular device to the right of the PTO. Anyone know what goes where? It won't even turn over now.

Thanks,
Karl
