I'm working on my 1972 911T. Well what started as a headliner replacement has turned into an all out anything related and while I'm at it syndrom. You know the story...

One of the related projects is to get the fog lamps operational..that, after deciding I needed a new crack free dash.

Here's my questions:
There are 4 terminals on the back of the Fog Lamp Switch. They are labeled:
1-?
2-?
3-?
K-?
Can someone guidance as to what wire should go to which terminal?

The exposed wires behind the dash (dash is removed) that are not connected are as follows:
1-There is a brown wire with a green tracer (interior lamp wire) that is connected to a power wire (has power when the key is on) that is yellow with a red stripe.
2-White wire with green tracer (same color wire at the fuse box for the Fog Lamps.
3-White wire with black tracer.

Any help would be appreciated. Thank you
