Post 13 shows picture of the heavy feed you are looking for.
It is a bit of a struggle feeding a heavy cable through but it will work well.
As has been mentioned avoid scotch connectors. it is best to solder or at least use the correct size crimp and ratchet tool.
Makes sure cable is the correct size for the loads and all will be well. I use the 13 pin and have done so since it was first introduced, mainly for a neat approach at the hitch but more so for the additional earth grounding connections.
