Ignition wires

[celgt4]

I am building my rally car and need to wire in a battery master cut off switch which in turn will be next to a ignition switch and starter button. I have to replace my ignition barrel with the starter button and I cannot seem to find what the different wires do and their colour. There was a post on here but as usual I cannot find it again. Can anyone help?
Cheers

I believe it's the yellow wire. I am about to do this myself next week, this is probably the thread you were looking for earlier
