Need Help identifying ac blower motor wires in home air conditioning?

So, my old blower motor started smoking, and sparking, I took it in, and bought a new one, the guy also sold me a new capacator with it, and hooked it up for me... BUT I'm confused which wires go where. I took pictures..

Answer:

we've appropriate air inspite of the undeniable fact that it works besides as Bush being the President for the previous 7 years. No offense meant, stereotypically conversing. yet we bough an easily air conditioner for our abode. Sweeeet. :)
The orange wire connected to the old capacitor can be removed and connected to the white wire. .Connect the black wire to the relay and the two capacitor wires as the guy that sold it too you had it.
Their are several ways to wire it.. If you want it to connect like the old one with 3 wires you go ahead and connect black to black and plain brown to brown and the brown wire with the white stripe to common or where the orange wire was. You would not use the white wire, tape it off (It will be live,you don't want a short) and out of the way,don't use it. OR go ahead and connect black to black and white to the common side of the contactor and connect the 2 brown wires to the new cap.You would also tape any other speeds like red (low) or blue (medium) off so they won't short to chassis or each other. Treat them speeds as if they is live wires. Tape them off away from each other and the frame.
A wiring diagram for the unit would help. I can't tell from the picture. But if you attach both brown wires to the capacitor, the black wire to the same terminal on the relay and the white wire to the contactor (large relay in the center with the two thick wires) line side that is the opposite phase of relay terminal the black wire is attached to the motor should run. If the white wire is on the same phase of the black wire, it will not run. You need that 180 deg phase difference between the two.
Is the orange wire on the capacitor in your picture attached to the top of the contactor? It is hard to tell. If it is, then on the new motor, the 2 separate wires that go to the capacitor (probably both brown), go to the capacitor, the black wire on the new motor goes to the same place where the original black wire went on the relay, and the white wire goes to the terminal where that orange wire comes off of the contactor. I hope this makes sense. A lot of older motors were 3 wire.
