I was just getting to that!
Thank You everyone for the help and suggestions!
Oh, and I never did find that junction box anywhere inside. I'm so skeered of spiders, I wasn't even going to try and look for it under the house.
But, with that tool I bought, it traced all the wires through the walls, and none of them gave indication of leading to a junction box anywhere. But, it makes sense that there would be. as these homes are delivered in two pieces with the sheetrock (*cough* GYPSUM *cough*) is already on the inside walls. How else would they do the electric afterwards, as there is not crawl/attic space above to bring the wiring down after the two halves of the home are bolted together. Im sure it is there, but yoy want catch me under the house looking for it!
Spiders and Bees (only because I'm allergic) are pretty much the only thing I'm afraid of, that, and freaky looking people walking around your tent at night while you are camping in the great outdoors!
Oh, and IanB, you are correct, I should have said receptacles (or sockets) and not plugs.
Again, thank you everyone for the Advice, Suggestions, and help in this matter. It has been solved!
