In fact the engine compartment blower got two source of power. I don't know why the fuse diagram did not show C5 but the wiring diagram does. There is a primary source of power directly from the current distributor to the fuse B4. The alternate route is to fuse C5 which is taking power from the fuel pump relay. That is why the fan can run to cool the engine compartment even after ignition switch to off because power is coming from B4 which got power from battery. It will modulate for 40 minutes after shut down to keep engine compartment temperature below 78 F. This function is control by the DME which is controlling the relay switchover between power source.....

thanks jpflip!!! I was looking at the Carerra diagram above at first...but I found the Turbo's diagram and it says "engine compartment fan (optional)". Your response now enables me to understand why that is. Interesting, I didn't know that until you explained just now.
