Can anyone point me to a diagram (or draw one and post it on here) showing which wires go where on the reverse of the key switch?

It's a 1994 400L 4x4 and has 4 contacts.

I've got two wires connected already - red and red/white - which allow the use of the head lights, starter etc, but the black and brown wires seem to cause mayhem when I attach then in any order! I believe the black and brown ones cut the engine out when the key is switched to off.

The reason I want to do it is because the bike can still be started with the pull cord, even when the ignition is switched off!

 

Anyone?
