Try marking up what cables you have ie purple position 1 etc do this with all cables (battery disconnected) and disconnect from the ignition switch, then with your multimeter set to continuity on bleep, when you touch the 2 test lead together the tester bleeps, go between the ignition switch terminals to establish the positions of the key, generally we have a common / normally open, goings closed when you turn the key, in other words between 2 terminals no bleep turn the key to the next position and it bleeps lets just start with this. If you check the wiring diagram for the ignition switch you should see numbers they are the switch positions regards Phil
