Please let me know if you need any further clarification on the video/situation. Any help/insight is much appreciated.
Ok I didn't watch the stones. Are you having problems or wanting to bypass for component removal? I can tell you this. Interlocks are used to disable the bus so it wont start up if the wheelchair, emergency doors or any other safety device is not in it's proper upright and locked position.
Some disable the fuel so it won't run- less of them disable the starter so it won't even turn over.
If you're going to disable them:
1) determine the operating position of each switch.
2) everything that is unpowered in that position can be disconnected.
3) anything that is powered must be disconnected and reconnected to the wire or wires that it powers. You determine this by testing for what becomes unpowered when you disconnect it.
Once you do that you can remove the device that triggers the interlock.
There's also 2 that are on the vehicle itself :
1) neutral safety switch: disables cranking in any range except neutral and park.
2) gearshift lock: won't allow you to move column shift out of park unless your foot is on the brake. On some GM cars the brake pedal switches go bad causing this. The Ford's you can turn off key and it will release the lock.
