You should not have to trace those wires. That is why in a post above I gave you voltage measurements to take, here is the deal
The ignition switch has of course
BATTERY power into it off the ammeter circuit. This is NOT fused
The outputs are as follows
ACCESSORY.......This feeds power to the switched buss in the accessory fuse panel, and is hot with the key in either "run" or "acc." This feeds stuff like wipers, heater, radio, etc
RUN or IGN1....This is hot ONLY in the "run" position, ONLY. This is normally dark blue
