You said you redid the wiring, I hope you kept the color scheme as it was before (or at least consistent - trailer wiring is usually "Black Pos | White Neg", not "Red Pos | Black Neg"). It's possible you have some black wires that are pos and some neg now... Make sure you know where everything goes!
This size of battery can release a lot of power in a hurry, welding things together, making sparks, melting, exploding, causing equipment damage and injury. If you're unsure of what goes where, get a second opinion from someone who knows about battery wiring!
Both of the prior responses are correct.
These are GC2 (golf cart) 6V batteries, you need to connect them in series to get 12V.
There should be one wire loose on both ends - that will go from one battery's Pos terminal to the OTHER battery's Neg terminal. You will not connect anything else to these 2 terminals. This will put the batteries in series and give you 12V between the free battery terminals.
Find the wire that goes directly to the frame, that will be Negative. Connect this to the free Negative terminal.
The other wire (eventually going to the converter's Positive terminal) will be Positive. Connect this to the free Positive Terminal.
The Jack wire will go to the same Positive terminal, and get it's Negative through the frame with no wire.
Notice I did not specify any colors - with it being a rewire, I would check and double check where everything goes before hooking it up. Labelling the wires for future reference would be good too!
Good luck, and here's hoping for no sparks!
