Long ground wire is a source of the ground loop. To be of the same potential both the HU and Yatour would need to have an equally short ground wires connected to the same ground point.

Power in, power out and the ground, yes.

Would I put this in the power line for the Yatour box? The power line for the radio before the tap off to the Yatour? Or the radio power line after the tap?

The Yatour doesn't have a separate ground wire. I think that it is grounded through the DIN plug.

Between HU and Yatour, closer to Yatour.

I think I said that before, but I also had to break off the loop for line-in for my central speaker amp as well. The whine was minor, lot less than through ground, but still.

Another question. Should I ground the filter directly to the car's chassis, the radio's chassis, or through the ground wire for the radio?

You do not need to ground it to the chassis.

Just hook to the radio harness' ground wire?

Hook to Yatour's harness. Either splice the cable or make your own male-female adapter. Solder noise suppressor's ground wire to harness' ground wire, cut +12v wire, one end solder to green (input), another to red (output).

The Yatour doesn't have a separate ground. I'm guessing that it is grounded though the DIN plug and the the DIN's shell. So solder the ground to the DIN shell?

Solder black wire to the GND wire in the cable. The idea is to feed the +12v through the noise suppressor.
