Can't figure out how to wire a Supco 3-in-1 relay into my fridge power supply. Seems like it should be simple, so I'm not sure what I'm doing wrong.

I have the 3-in-1 wired to the compressor. But I have four possible wires I can connect for power. One is blue, and is live. There is a white wire which seems neutral. There are two black wires. The black wires (one smooth and one ridged) appear to just go to the compressor fan. 

I wired the blue and the white to either power "in" line on the Supco 3-in-1, but the compressor doesn't seem to turn on and the compressor fan is off. The interior lights and interior fan turn on. I cycled it through a defrost cycle just to see if it was in defrost, but it is not.

I have watched about twenty videos on how to install the 3-in-1 but none of them explain how how to wire the power. They assume you know how to already.

I called Supco tech support but they referred me to the fridge's maker. 

This is an Admiral model number HMG-22844.

Never mind, I think I got it. Here, blue is hot, orange is neutral, connect them both to the 3 in 1 and the compressor came alive. 

Wire the two black wires to the same connections, and the compressor fan came alive. 

Seems to be working.
