Wiring diagram for Craftsman Garden Tractor

[pinetucket]

I have the wiring diagram for a Craftsman Garden Tractor 917287031 but in comparing it to the mower, I seem to be having a problem. Too bad they didn't color code them. Just under the "dashboard" of the mower from the switch to where the cable ties are connected to the body, there is one white wire with a plastic connector, single plate inside that is not connected to anything and has become undone. Do not know where it goes. Can't find a female plug to plug into it. Thought it might be where the 20 amp fuse goes, but alas, it won't fit. Can anyone tell me where this wire might go to and exactly what this wire is?
