Cool 1995 Murray Sentinel Ignition trouble

I have a 1995 Murray Sentinel lawnmower which has ran great until recently. The ignition switch where the key is placed was made of plastic and has recently fallen apart. It is in three different pieces. I have tried searching for a new ignitiongqz ` with no luck. Following this I tried to bypass the ignition all together and hot wire the lawnmower. This also didn't work. I can not find a wiring diagram or a replacement part for this mower anywhere. The specs are as follows if anyone can help me get this mower running again with or without the use of a new ignition and key. It is 15 years old so info is hard to come by, but the mower ran great so I don't want to part with it over a stupid plastic ignition.

1995 Murray Sentinal
Model F3912000
Code 5090

12HP Briggs and Stratton engine
Model 282707
Type 0110 01
Code 9503284D

The wires are:

1 Red wire that goes into the engine
1 Red w/ White Stripe (w/ fuse) that goes to the battery

2 black
One goes into the engine
One goes into a small wiring harness that is installed under the cutting deck. (it also has a small push button on the end of this wiring harness.

1 yellow wire that also goes into the wiring harness under the deck.

2 light blue wires
One goes to the headlights.
One goes to the pressure sensor under the seat.

Please help get this mower going again before Code Enforcment pays a visit! Thanks for any help you can provide.

Any switch could be made to work if you understand the wiring and the switch functions

Thank you for your help. This does appear to be the exact wiring. Problem is it doesn't show the wires going into the ignition switch. The part number for the ignition switch helps a bunch though! Thanks alot for your help.
