I've searched and have not found the answer to these questions

1) Where is the fuse for the upfitter 50A, 8GA power connection in the passenger B pillar?

2) In that same location I have a fuse box that has a single 10A fuse that is supposed to be for the "rear heater prep". Does anyone know the function of that circuit? I don't have the rear heater prep package, that I know of...

Very good questions!

1) I think I saw the 50A upfitter fuse attached to the van battery at the point that the wire to the 50A connector is connected to the battery.

2) I have it too... no idea what it's for. I have no rear heater either, that's for sure.

I took a look in the battery area and in fact there are a few fuse looking things (fusable links?) connected to circuits going to the battery. It's silly that I cannot find documentation on these (or perhaps the fuse ratings don't match what is in the book).

I still have not figured out the 2x40 amp fuses in the B pillar. I suspect those are for the heated mirrors, but the manual says they should be 20 Amp.
