Its all the same in terms of wiring, have a look through the manuals section for your wiring diagram.
I mentioned the generic 3 position key because they are small and can be hidden under the dash or where ever pretty easy. and that way you dont have a bunch of toggle switches to mess with to get your off, accessory, and on. Then you just run a button to the starter relay

Im partial to a vintage style floor starter. Start the car with both hands on the steeringwheel is a bit of a party trick now days.
