Refrig making a lot of noise

The motor kit had only two wires coming out of it. The existing one in the refrig had 6. I spliced the 2 red to one black on the new part and 2 white to the other black wire on the new part. The two green I attached to a screw. I left the 6 wire harness in place just cut off the plug piece that went into the old motor, and spliced all my wires.
Worked great!
