In regards to the Replacement Converter for Parallax/Magnetek or WFCO RV Power Centers part # PD4645V, the fused slots on the control board are very easy to hookup. If you're swapping out an old panel just make sure to label each of the wires before removing. Then, you can connect the old wires into the terminals on the new board with a screwdriver, just make sure you then assign the correct fuse to said wire. It does not matter which slots you places the wires in, just make sure the fuses match said wire from the old board. There could very well be more slots than your old board, they can be left blank and used latter down the road if needed.

That said, it's really best to seek professional installation of the panel or converter section if you need assistance as these should be carried out by a licensed professional .

@Pamela Hey there, that is typically the blue pos + going to battery positive terminal. I recommend testing or having an electrician do so to verify. You can cut off shore power so there is nothing energizing the converter, then disconnect the blue wire and test if there is voltage there. If 12v there then it is connected to the battery positive post.
