Kancil ignition key switch wiring

[cyclonite]

Hello guys, today my friend lost her car key so I had to hot wire her car for her. Just wanted to ask you guys what the blue wire is for? At the plug connected to the keyswitch, there's 5 wires.

1) red stripe
2) green stripe
3) yellow stripe
4) black
5) blue

I connected wires 1, 2, 3 together and all the accessories and lights could turn on. Then I touched these wires together with the black to engage the starter and then can drive back. But I never once used the solid blue wire. what is it for?

Thanks.

Yo man, I just tried. It's true la... red connect to BLUE = ACC. you're so cool :)

Then what's the difference between the yellow and green one? I know one lights up the indicator lights on dashboard + air cond. The other one is neccessary otherwise the car won't start at all.
