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!
