Red Battery wire goes where?

[Hollisterbulldawg]

On my 2012 5th wheel, the two batteries are wired in parallel. But the red wire does not go anywhere. The negative is grounded to the trailer frame. I think the positive side is missing a connection wire to the trailer. Can someone tell where it should be connected to? Thanks.

You should wire it like this if it is two 12 volt batteries

I believe he is looking to find out where the red connects to some kind of junction box or power panel.
The previous owner probably disconnected it from a 40 amp fuse or something similar.

Can you clarify, do you have a cable connected to the battery but not connected on the other end, or is there no cable apparent to connect to the battery? Is this a new to you camper that you bought with no batteries or did you replace the batteries and forget what goes where? A pic would help folks help you.
