Maytag Refrigerator Parts Replacement Question

Background:
Refrigerator/freezer stopped cooling, and I heard clicking noise every several minutes. The overload/relay kit was completely fried (almost melted).

Question:
The connections to the overload/relay kit are black from the meltdown but appear in fine shape. I would feel more comfortable replacing those, but am confused on the parts since there isn’t a clear picture on the parts list.
Overload/relay kit part is: AP4009244

What other parts do I need?

I assume the wire harness (AP4069288). (assuming that is the one with blue/orange to fan, electrical outlet connection, and blue/orange to overload/relay kit).

The other white/orange into the overload/relay kit is connected to a small box on the side of the refrigerator. Is there a replacement cable for that?

The simple answer might be just replace the overload/relay switch because the other cables should be fine. However, I want to make sure that it is safe and that the cables, by default, shouldn’t have to be replaced when the overload/relay kit melts down.

Thanks for your help.

The small black box on the side is trhe run capacitor which must be wired in the new start device, just like it was with the old one. If you can see both ends of the harness, should be easy to replace it.
