Where does the reverse light harness plug into an a833

I cannot seem to find where the prongs actually plug into the transmission, because when I got this I discovered they were just unplugged and I’d rather plug them in while I’m down here
I looked up on a search engine for a A833 trans cutaway image and found it is behind the bolted cover by the tail housing on the main body.
There should be a threaded connector for the plug in
