Snapper rear bagger....Burnt wiring harness

I posted this in the general mower section, with no replies. I have a 10 HP rear engine Snapper that has a burnt wiring harness. Let me try to explain. Down near the oil dipstick tube, there is a white plastic fitting, with 1 wire in ( i think) and 2 wires out. Red wire, white wire, and black wire. The wires going into this fleeing melted. Can someone look at my picture and tell me how to repair this ?  I can use new squeeze on fittings, but I need to know what goes where. I have enclosed a picture.
