I'm looking to sort out some electrical gremlins in my car.
This is an 1991 FC turbo 2 which is almost stock, at least electronically speaking.

The previous owner installed an aftermarket alarm with one of the cutoff installed on the starter wire coming from the ignition switch.

I'm looking to remove the alarm so i've looked into it and i've noticed a weird thing.
In the documentation, ignition switch is shown as this


But mine is like this : (picture taken of an ignition switch referenced for a 86-88 model on atkins rotary


basically i'm missing the plug with the pins K1, K2, L and E.
Is that normal ? I can't find anywhere what those pin connect, do you have any information ?

By the way my car has no airbag and is not a convertible. I wonder if those pins could be linked to that.

 

I'm not really sure what you're trying to say, but this is the ignition switch harness for a US S5 coupe with MT (https://www.rockauto.com/en/moreinfo...sn=546&jsn=546). The S5 harness has white connector with pins configured as 4x1. The S4 harness has white connector with pins configured as 2x2 (https://www.rockauto.com/en/moreinfo...192317&jsn=630). I'm not sure what these wires are for. Other than that, I think all the wires in both switches are identical.

 

Hum sorry i didn't realize that there was actually 4 connectors on the second picture. I (thought there were only three connectors...

So basically i have one of the connector that is missing on my car and i can't understand why...

 

The wires are for the key cylinder illumination.

 

The little light behind the orange plastic plate ? I have to check were it connects on my car.
