1973 911 - Seat Wiring

Hi guys-
have been restoring my 911 and backdating to ensure all features of the 911 are in working order. Here is a picture of a wiring harness that connects to the seats of the car through the dash.

I am assuming it has something to do with the seat belt light and buzzer.

As you can see mine are completely fried, HOWEVER I can't seem to find them anywhere...anyone have info on this???

Thanks!
