i have an 88 dl wagon and i think the ignition switch is intermittant . the fsm i have doesn't match what is in the  car,it shows three wires and my car has five wires but it seems the ign switch runs most everything,but the only thing that works all the time is the starter,and lights. i don't want to start throwing parts at the problem.  i've  checked all the grounds i could find and i have power when it suits the car. maybe i need an exersist. the stuff works until i go to another system then the first part doesn't work again damn. i'm poor i can't afford test meters just a test light. i haven't even started on the front end yet. 

just been looking at my 84 and 89 Brumby ignition switches, not the wires just yet BUT, Logic says has to be:

 

battery power 12V all the time

a 12V accessory output

an 12V IGN output

starter motor 12V output on the spring tension position

 

if poverty is an issue, splice in four light bulbs to each circuit and mount in a povo cardboard box sticky taped to the dash top, drive and observe if a circuit drops out and if light does as well you have your gremlin !

There is a fifthe contact on my switch, not sure if it is five wires though - likely is - mo idea. I think the switch is marked in the casting right next to each male spade terminal and the odd one out has an R on it.

 

 

and editing before I finsish ...

 

I have two different EA82 ignition switches just beside me - no spade terminals on the back like EA81

 

One is pink plug  which loooks to be , BLACK, BLACK/White( or yellow trace),BLACK/RED trace, fat BLUE, fat WHITE

other is black connector is BLACK/BLUE , BLACK/RED, BLACK/WHITE,, BLACK /YELLOW and plain BLACK

 

no help what so ever, but think now all have five wires except your diagram

thats all well and good but what do the wires go to?
