So, you replaced the HVAC blower motor for cabin air? Right? If so, you should only have two wires going to it, a red and brown or blue.

I took the photo below of my plug for the blower motor, I have the evap case out for evap and elements, the car is a 1992 300 TE. I don't know if your plug is the same or not. It sounds like you have the same number and colors for wires.
