Solar wiring

You do need a reverse polarity pig tail if you want to plug your non zamp panel into the zamp plug on the side of the pod.

Hi Leo and McCarter.  Thanks for your replies.  Well, that's exactly why I asked the question about the "reverse protection diode".  Most systems have that protection built in, so that if you accidentally hook the system up with reverse polarity, the diode prevents current flow, thus saving an expensive controller.  I just looked at the polarity of the port on my Rpod (2019 model), and it appears that it is wired backwards.  Typically for safety reasons, the positive terminal on a ZAMP connector is the hooded connection, where the male is negative.  That method is used to prevent accidentally touching the positive pole to something valuable, and causing a short circuit.  I will ask Forest River if they have a schematic of that system, and if so, I'll post that location here on the Forum.  Thanks again! 

When I wired my solar system in our 2009 Pod, in addition following the red/black convention for polarity, I connected the plugs such that the negative and positive cannot be mixed up because the male/female orientation is reversed, thus the negative plug cannot fit into the positive.  If the ZAMP connector is not configured this way, then you need to be really careful or you can swap the male/female orientation on one wire to prevent accidental mixup.

As others have stated, the zamp connector goes straight to the battery(ies). You can just reverse those two wires at the battery(ies). If they are the wrong color, you might get a foot each of red and black shrink tube, and put the "proper" color on each wire.
