A lot simpler. 12 V from fuse #3 in the cabin fuse box goes to the two heaters. The other side of the heaters is connected to the switch, which grounds that line when the heater is turned on.
I have both the FSM and the Haynes for mine, and several others in bits and pieces. There's no question that the FSM is well worth the time (download, organize) and the (in my view very reasonable) cost. The Haynes focuses more on "how to" for repairs and maintenance, but doesn't provide the background detail that can be useful when troubleshooting. Moreover, it often covers several years and models, but doesn't alway provide information on all. Nevertheless it is good in what it does provide, so it and the FSM complement each other.
