Alright, finally got some time on my hands, got 3 ignition switches, tried them, and it appears that the problem still exists. I'm assuming there's a short circuit somewhere, as I opened up a ignition switch and figured out how it works. On the picture, it shows those numbers and/or letters labelled next to each pin. What does those numbers stand for? By any chance the amount of amps that travel through them?
With a good look on the inside part, the 2 pins with 15 are linked, and appears to touch a terminal in the middle when the key is turned to the preglow position. The one labelled P and P30 are the buzzer that indicates you left your key in the ignition. The two that says 30 on them seem to be linked to the middle terminals. I assume the 50 is for start and the R for accessories (power windows, radio, sunroof). Can anyone confirm this for me? I do not have any W116 repair literature. Thanks.
