Smoke under left side of dash! Options

[eyecolor]

I just got my 1975 914 off ebay last week and new I had a project. When I started it up and drove for a few minutes I noticed the headlamps came up but not on, the dashboard lights began to fade and light smoke started to drift out from under the dash.

After the car was off, the headlamps stayed up and the small amber outside lights were on.

I finally pulled the battery and the smoke and lights left me. The headlamps are in the up position still.

I assume a short, but I really don't know where to start, so as a new member I hoped I could turn to a few good souls to give me some "pointers."

Thanks
