really weird electrical problem..., ideas? Options

[siverson]

Hi - I have a strange problem with my six conversion that's popped up.

My ignition key got stuck/melted in the "On" position. Was driving the car, everything was fine, started to smell something funny (thought it was under the dash, but turned out to be the white plastic thing the key plugs into that the wiring loom then plugs into), pulled over, and couldn't turn off the car. Key is stuck. I stalled the car to stop it. Couldn't start the car or switch it off.

Brought it home, checked things out, removed the key/ignition switch. Nothing seems wrong except that white ignition switch module melted! Everything works fine, and I haven't changed anything in 2,000+ miles, no fuses are blown, and as far as I can tell I have no shorts in the electrical system.

To test things, I pulled the module and then just ran a wire between two terminals in the switch to "hot wire" the car. Starts and runs fine, but the new "hot wire" gets really hot when driving!

Question: Why would there be too much current being pulled through the ignition switch all of a sudden?

Any suggestions on where to start to diagnose?
