Below is the wiring diagram for connecting the resistors. I choose to mount the resistors to a small aluminum panel and bolt it next to the fuse block. The wires are simply soldered to the resistor ends. Once everything was completed I actually got much higher airflow from the blower motor because of the larger primary wiring and good connections.
What is the reason that 2) 0.27 ohm resistors are not used? Is it just due to the Wattage? I would think 2) 100W 0.27 ohm resistors would work, correct?
