Opened up the black box labeled LPT30 and it is the auto switch as Grumpy stated (thanks Grumpy) according to the labels inside the box. I have no way of knowing if the rig had a Iota 30a auto switch when built but I don't have one now, so that is the important thing.
I traced the black wire with orange tape on it and it dead ends with the white & black wires in picture 2. I taped up the ends of the all the wires, the black one is not attached to anything on either end, and the white wire goes somewhere under the floor, and I taped up the end of it as well, just to be on the safe side. thanks to all for suggestions and help.
