Hello all,
I got a protect blower motor with two brown wires,I know the brown wires go to capacitor but where do I put the other wires to. One red,one white, one black, one blue. It is connecting to a rheem furnace on the board I got a m1, cool ,heat , neutral.

You will need to look at the wiring diagram which should be on the air handler. There is no code for most wire colors. Typically black, blue, red and purple are current carrying, green, green/white are grounds, white is neutral. Is "protect" a brand? Look on the endplate. My guess is the colors would be different speeds and possibly rotation.
