Original had 3 wires coming from the capac instead of three labeled spade connectors. two red, one brown. brown to b, 1 red to c. any wiring help?

What I did was had label facing me. And I removed one wire at a time matching each move

My furnace makes a big hum when starting the blower motor. Could the problem be a weak capacitor?

Only if it has a weak one. These are normally found at A/C compressors.
