Thanks for the info, metroschultz. I finished the wiring tonight. I used the blue and black wires from the fan. When I tested it, it didn't matter which wire was connected to positive, it spun the same speed. Actually, with the relay kit between the fan and the battery, it seems to spin a bit slower than it did when directly connected to the battery. It still pulls a ton of air, so it should be fine.

After the install I found that there was not enough clearance between the fan motor and the water pump pulley as it would rub in certain situations. After modifying the fan shroud and remounting it higher on the radator, it seems to be alright. I can actually notice a slight difference at low RPMs and when starting from a stop. We'll see how it affects gas mileage, but I think this mod is a winner.
