1/8” Pipe Plug?

I am almost complete reassembling my small block and I notice a 1/8'' socket head pipe plug laying in my tool box. It has orange paint on it so I assume it's from this engine but I don't remember removing it.

Any ideas of where it may have originally been located in the engine, or a fluke / random plug with orange paint? I kept all the other take off parts in bins, cans and a dedicated tool cart, so it is also random that the plug was in my tool box.

I read this link too but I think this plug is much smaller then shown here, it's the size of the oil pressure sending switch port by distributor.
