I do think this was a PO mod that either went afoul or was used for awhile and then disconnected. No way this is factory. Main reason I think this is PO mod is the main wire feeding camper is red for the pos side like it should be and this iwire is white and slightly larger diameter. It's a stranded cable and it's huge. Don't know what the heck was hooked up to it but Its actually wedged between a crossmember and camper floor. Makes me thing some welding took place there! I'm pulling that cable as soon as the rain is gone!
