I get it. Sorry for the brain fart, I misunderstood what you were saying. This intrigued me so I've done a little more digging and what it looks like is that there should be a resistor block on the blower. The body harness plugs into it with a two conductor plug (the black and white wires) and then the blower motor plugs into it with a single conductor. This is one of many photos I found.
