My setup eliminates the key completley. I have two switches:
- ACC - the 1st position of the key
- IGNITION - the 2nd position of the key
I have a Start Button, and a Kill Switch.
To start the car, there's no need to set the ACC to on. Since I'm building a 'race' car, I don't have any music in the car. But if you plan on putting this in a daily driver, you could find this switch usefull, since it controls power distribution to your head unit.
Fasten your seatbelts! We're taking off!
What do we need?
- On/Off Switch [x2]
- Start Button [x1]
- Kill Switch [x1]
- Terminal connectors
- Wire cutters
- Wire strippers
- Wire crimpers
- Isolation tape
- Plasma torch
(yes, #5 is a joke)
Ok, so what's the procedure? First take off any plastic you have under the steering column. Then find the wires comming out of the ignition switch located on the left side of the column. (The ignition lock is on the right) Follow the wires until you come to a connector. It should be attached to the steering column with a plasic holder. Disconnect the connector, and then about half-way to the ignition switch cut the wires. (Make sure there are red, green, black+yellow & purple wires there).
Here's a drawing:

Blue line marks the cut.
Ok, now, here's how the new components go in:
A - Start Button
B - ON/OFF Switches
C - Kill Switch
Be sure you isolate every connection! Stick the connector back where it was, and try it! :)
Probably, it would be a good idea to put a couple of circuit-breakers (fuses) in there... but, hey, it's up to you.
Hope this helps. If you have any questions, do ask.

Switches, wires, pliers... :)
Ah! Here are the connectors (after disconnecting)
This is the interesting bit.
In a day or two, I'll post a DIY for the dash panel that will hold my switches :)
A couple of cool things...
Start button for $33.11!
Kill switch for $14.95!
