6Ohm resistor is a blower fan motor speed control resistor (coil it resistive wire filament) that is triggered on rapidly by the relay to prevent buring out and consistant power draw, I built this out of the speed selection relay and blower motor resistor at 3am this morning, get's hot enough to yellow your skin on contact like a soldering iron would.
12VDC 2A 24W
I know those numbers don't look all rediculous for a car powered heating option, but this is just enough to take tye edge off while you wait for the engine heat to build up
This makes a nice tone by the way, I'm posting pics to the G+ community in a few minutes
Enjoy
