I have completely rewired my car and the only thing I'm having a little trouble with is the heater motor wiring. I'm looking to just have a high and medium setting for the fan speed. I am using the stock wires that go to the blower. I originally wired in a relay to switch 12V to the motor for the high setting but the wires were getting hot since it's pulling too much current, but this is how the stock wiring seems to run. I havent messed around with the MED steeing yet but it just seems to run through the heater resistor. Below is the diagram for the blower motor. Any help would be great! i'm open to ideas.
