I am thinking about adding heated seats and am thinking about the wiring. So here are my questions: The Rear Fuse box has some spare fuses. Are any of those switched with the power or are they always on? Are there suggested fuses for two heated seats? And what would be the best way to ground them? Is there a ground screw somewhere back there? Alternatively, I've thought of tapping into the rear cigar lighter, after I switch the fuse up front so that it is switched with power. Is that a good option? I'm sorry for all of the questions, but I don't want to do this until I am absolutely sure of what I am doing. I appreciate your input. Jay
