Yeah, somethings been added to that connector. It should have an orange, red, dark brown with white stripe, and a light brown with white stripe.
The light brown wire with the white stripe comes from the alternator. The brown wire from the alternator goes to CX of the bulkhead connector. Then from interior cx the light brown white stripe wire goes to the ignition switch.
Now you need to fix that wire. Then figure out what the heck those other two wires are doing. They should come out because I don't think they're fuse protected.
You know in the mid 80's you could pick these cars up for practically nothing, so people didn't think twice before doing surgical "repairs".
That light brown wire with the white stripe doesn't look like it's fuse protected or have a fusible link protecting it. It goes straight from the alternator to that place in the ignition switch.
