I need some help identifying the functions of the pins in my ignition switch. Some time ago my ignition switch started to malfunction. The issues I experienced were failing to switch into the desired mode and bouncing contacts (dash flickering). From the electronics point of view, I understand how undesirable flickering is and how the contact bouncing can over time cause damage or overheating of the terminal. I bought a replacement on eBay. Since it is a cheap variant I tested both to see if I get similar behaviour. I summarised the results below. I am 100% sure that pin 2 is +12V and I am almost certain what the functions of pins 1, 4, and 6 are but unsure about pins 3 and 5. If someone could confirm my assumptions or link some wiring diagrams for my vehicle I would be very grateful.

Before plugging in the replacement I would like to double-check the function of each wire. This would also benefit me if I decide to install an engine start/stop button kit. Many thanks!
