I think I could tie it into any positive 12 volt wire and it should work as it is supposed to.
I'll research more on this.

I think that wire may be the wire to your battery. On the WFCO board the positive from the converter lands on a lug that feeds all the 12V fuses. The battery wire lands on a different lug and feeds the 12V circuit via a pair of reverse polarity fuses.
The thinking is that if you hook up your battery backwards, the reverse polarity fuses will blow and protect the converter and the 12V circuits in the trailer. The reverse polarity fuses are built into the new converter so the ones on the circuit panel are redundant.
I'm thinking that you won't get any battery power when the converter is off if you don't hook that wire in.
