HOW DO I ISOLATE ACCESSORY WIRES FROM IGNITION?

1997 Mercury Sable • 150,000 miles

When the key is switched back to accessory function, radio and wipers work. When key is in run position, speedo, tach, wipers, cruise and radio doesn't work. All fuses are good and relays are good. I replaced ignition switch thinking that was the problem but no luck. Its not the lock tumbler itself and I operated the ignition switch by hand and got same results.

I would look at the fusible links as one may be bad causing these systems to not operate.
