Oh...Just in case anyone ever models their own custom harness off the schematic I posted in post #7 of this thread...
One thing to note is that there is no voltage stabilizer or temp gauge depicted--There are provisions for a temp sender and gauge, but the rover this harness was meant for doesn't have one nor does it use a stabilizer for the fuel gauge. Easy stuff to slip in to the plan, though.
