i was curious it anyone hooked up some toggle switches to activate the fuel pump and what not and then have a push button to start the truck because i think it would be pretty neat to have one... there is nothing wrong with my current ignition but like i said it would be something different.

You still need the key to unlock steering.... So why bother.
Research how to put a remote starter in your truck. That will give you the main circuit to put a RELAY in parralel with and then you'll need a diagram possibly for the misc things that may not work. The push button is just a bypass of the start position, and will go directly to the solenoid.
It's fairly easy, but you should use 2 relays because everything is powered through the switch. One relay will be maxed out. Or get a big battery switch or a marine relay or a western plow relay to use.
You'll be liable for your own work. Find a wire diagram for ignition switch and see if you still want to do it.
Well if the only thing you want to run is the engine, its easy. Find the ecu power wire, tsp into it and add a switch. Problem with that is, NOTHING ELSE WORKS. That's why I said tap into ignition switch. That way radio and heater and dash works.
Starting the truck is easy. It's 1 wire to control EEC relay under the hood, fuel pump and engine control will follow once the computer gets power.
You still haven't convinced me how you're getting around the steering lock... You still need a key, you still need to turn it3/4 the way around to get everything else powered up.
I had a full manual setup in my 97 Thunderbird... steering lock can be removed if you take the column apart. I don't remember what I did but it wasn't hard. I had rocker switches for primary and auxiliary electrical. Primary did the same as turning key switch to Run except no accessory power, which was what the aux switch was for. Also had On/Off switch for fuel pump, Hand/Off/Auto for radiator fan and Hand/Off/Auto for converter clutch.
Now, my F-250 had a bad starter circuit in the ignition switch and I was broke that week so no buying parts for me. Since I work with industrial controls, I just so happened to have a 22mm pushbutton, which I added just on the starter circuit.
Seriously.... Get a wire diagram for the ecu.
There is only 1-2 wires that need power when key is on, put a toggle switch for those wires. When the ecu has power, it will turn the fuel pump on.
Then a push button to the solenoid and you're done.
Figure out how to safely get rid of the steering lock and then come back and ask if you don't understand still.
