1965 Dart issue!

On my 65 Dart GT convertible last something strange happened.
When I put the key in the ignition switch and either turn left (accessories) or right (ignition on) the windshield wiper starts! The windshield wiper switch is off of cause.

When I add a test pen between the switch and the body the test lamp goes on.

Does anyone have a good switch and can tell me if the power goes on the switch, which outlets should have power at that moment? I suspent the outlet to the backup light switch. And yes, my works too. But between my two switches I have power on two different outlets on them.

I can't figure out what the heck is wrong!!

Any help is gladly appriciated.
