Need help wiring new ignition switch.

[Wintermute]

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.

Pin	Colour	Function
1	Red	Starter
2	Purple	[12V] Main
3	Blue	Alarm OFF?
4	Green	Radio/Fan
5	Gray	Dome lights?
6	Yellow	Dash/Windows

New switch	Old switch
OFF (key out)	OFF (key out)
2 - Nothing	2-5
Acc	Acc
2-3-4	2-4
ON	ON
2-3-4-6	2-4-6
Start	Start
2-1-3-6	2-1-6
OFF (key in)	OFF (key in)
2-3-5	2-5

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!
