You dont really need a wiring diagram. Just re-route the ‘starter’ wire to the solenoid via the inhibitor switch. Check the switch is open for all gears, and closed for park. This prevents you operating the starter in any gear. (not sure about neutral though, may be open or closed).

Note: the switch needs to be in good condition as there is a lot of current through the solenoid. A poor switch can lead to starting problems.
