I need to know what wires hook up to my coil in a 1650 cub cadet

I'm not able to reconcile pto wires and a 1000 42.

What is the model number on the label underneath the seat of this unit?

They are on each cylinder head. There is a wire from the coil to each spark plug. Remove the wire and you'll see the spark plug

The wiring is in the operator's manual.

Customer Service Cub Cadet

remove the top cover from the engine and remove the small wire from the coil if still no spark the coil is bad

you may want to check the coil. under the coil there is a wire (kill wire) unplug it. try to start it, if it starts you have a bad wire somewhere. if it don't the coil is bad and needs to be replaced.

Check and replace the coils.
