My freind had a panel of about 10 switches, I asked him what they were for, said you had to know the right switches to flip or the car wouldnt start. Worked well to, he had a way of rigging it so that he could change the 'combination' to.
They were switches to a lot of stuff to, everything from the fuel pump to the ignition itself, flip the right switches everything is on, but flip the wrong one it'll cut the circuit.
