Dash Wiring Harness Mystery Baby Round Connector

So I spent last night understanding my new reproduction wiring harnesses. Yes I bought all the major ones (Dash, Engine, Front Lighting, Rear Lighting). Anyway, with the wiring diagram on my big screen TV and the continuity function of the digital miltimeter I have determined where every single connector plugs in... except for one of them and can not find a logical thing listed on the diagram I haven’t already traced out to a different connector. So this connector is small, round, white, and has three pins on it, and it is fully taped in the harness so tracing a wire color isn’t possible, and random tests with a multimeter yielded no beeps of where it leads to... and that could take hours to go through. So in the picture below if you know the answer please tell me, the suspense is killing me. I am not going to be installing the harness until next month and I can’t wait that long to find that on my own lol.

That's strange. I don't believe I have ever seen a factory connector that looks like that. Looks like something you would find with a aftermarket radio or the like. LOL tape it off if everything works and you don't have anything to plug it into. Is it just power and ground and is it switched or direct?
