Some of my wires have come loose on my key switch and don't know where they go, does anyone know where I can get a wiring diagram for LX172

Hmm!

That's like asking for do you know where I can get a wiring diagram for my car, washer, TV, toilet, edger, radio, printer, computer etc.

We need a little more info.

Sorry new to this, it is a Lawn Tractor John Deere LX172
